YNYS WITRIN - Episode 3

Level by Monika Kunze (Miss Kroft)

Walkthrough by Phil Lambeth, to supplement the outline provided years ago by Monika Pietsch (and which follows this walkthrough).

Geographical information (from an online resource): Glastonbury, a small town in Somerset [a county in SW England], is surrounded by a grouping of hills. The tallest of these hills is known as the Tor, which happens to have an old stone tower on the very top which was once a church dedicated to the archangel Michael. Close to the Tor is Chalice Hill. Wearyall Hill is a long, narrow ridge that points towards Bristol Channel. Finally, there's Windmill Hill which faces the cathedral city of Wells and just below are the ruins of the medieval abbey. Before the land was drained for farmland in later Christian times, the hills around Glastonbury appeared as islands from the West. Today's river Brue was once the deepest channel in the shallow swamps and allowed boats to pass. The ancient name for the Tor was Ynys Witrin, which means "the Island of Glass." But this "island" is more widely known from Celtic lore as Avalon, the Apple-place and the isle of enchantment.

NOTE: Be sure to start the game with the savegame.0 included with the level download, so you'll have all accumulated (and needed) pickups.

Level 1: YNYS WITRIN - EPISODE III

After the opening flyby, run forward and pull down the wall switch to open the gate. Enter a graveyard and avoid stepping on the slabs lest you awaken a host of knights who will cause you much aggravation as you attempt to negotiate this area. However, you can pull up on the Celtic crosses without incident, so do that with the nearest one and take a running jump W to the next one for some revolver ammo. Look N across the graveyard and you can see a TORCH on top of the cross there. Remember its location and hop down to the ground. Go through the W archway (the crate and pots are empty) and shoot the NW wooden barrier. Follow the short alley to a water hole on your left and jump in (noting for later the overhead ledge). Swim down and follow the passage to a ledge where you can pull out.

Jump into the pool and swim across to the other end. Pull out onto a near corner of the NE pillar (to avoid the darts), turn and locate three underwater gates in the W wall. You can shoot the middle one with the combined revolver and laser sight that you brought with you from the previous level (assuming you did as instructed and used the builder's savegame to start this level), so do that and swim through the opening. Loop around to the right or left and pull down the ceiling lever in the corner alcove. There's a companion ceiling lever in the opposite alcove, so go there and pull that one down as well. Return to the main pool, pull out onto the SW pillar and swim back along the passage to the water hole. Pull out to find that the E gateway is now open.

Go there and shoot a crocodile in the shallow water. Pull down the wall switch in the far corner and exit this room. Jump to grab that ledge above the water hole, pull up, turn around and see that the wall torch has been ignited. You can take a running jump and grab from here, but you won't be able to do so while carrying the torch. Go back S along the alley and note for later the closed door ahead that requires two star artifacts. Return to the graveyard and pull up onto the NW Celtic cross. Pick up the torch you saw earlier and take it with you back to the S alley. Back flip to the W ramp and jump off to land on the E wooden walkway. Use the flame to light your torch (don't stand too close) and hop down to the alley. Return to the graveyard, turn left and locate the suspended boulder between the stone buildings. Light the rope and get out of the way as the boulder is released. A door is now open in the E wall, so go up the stairs there and enter the building.

Step out onto a high ledge overlooking a lava room. Take a standing jump forward to grab the ceiling, then monkey swing across the room. Release over the ladder, grab and climb down near the bottom. Back flip onto a tile and turn to face NW. Take running jumps from tile to tile, working your way in a counterclockwise direction. When you reach the tile next to the S wall, look up to find the mounted lion's head. Shoot the gem in its mouth to open the gate in the N wall, then jump back to the previous tile and N to the tile next to the open gateway. Scoot inside and follow to the intersection. Immediately hop back as a boulder rolls down, wait for it to come to rest and then go left up the ramp. Turn left into the side passage, pick up the small medipack and pull down the wall switch to open a nearby door. Go back out and follow the ramp to the lava room. Step out and then hop back as another boulder is released. After it has rolled past, go up the ramp and pull down the wall switch to open a door back in the graveyard.

Enter the open doorway to your left and follow the passage to a ledge overlooking another lava room in the woods. Jump NW to the sloped limb, slide down and grab the edge. Pull up and take a rolling back flip to grab the green wall strip. Climb up to the crawl space, release for an instant and grab to pull up into the crawl space. Lower Lara down the other side and drop down to a wavy tree root. Take a running jump SW and return to the graveyard. Loop around to the left and locate the open doorway. Go inside with weapons drawn and shoot two jackals. Turn around and pry the GOLDEN STAR off the wall. Exit this building, turn right outside and go through the archway to the closed SW door. Pull the stone block from the wall to your left and push it aside. Enter and go S along the shallow water channel. In the next room, start your long climb up by pulling up to the wooden ledge in the W wall. Jump and grab from ledge to ledge until you reach the high opening in the W wall. Hop to the opening, shoot the window in the far wall, step onto the slope and jump off with grab to glide into the W opening.

You can see your prize directly in front of you, so run forward and pry the second GOLDEN STAR off the wall. On your return trip, hang over the lava, pull up and reverse roll, then take a running jump without grab to land on the edge of the higher E opening. You can either use the same ledges to get back down, or you can jump first to the ledge in the NW corner and get to the highest ledge in the NE corner for some revolver ammo. Take a series of safety drops from there to the floor. Go back through the water channel and loop around to your to insert the Golden Stars in their receptacles. The iron door between them opens, so go inside and follow the passage through some cobwebs to a new room.

Get the revolver ammo near the NW corner, then go to a caged area at the NE corner (passing a closed door requiring a gem artifact). Go around to the right, and crawl into the semicircular opening in the S wall. Climb down the ladder at the end of the passage and crawl in W. Crawl along the passage past some steam blowers and pick up GUINEVERE'S JEWEL. Take the nearby N branch and continue crawling until you reach a ladder. Climb up and crawl into the caged area from the back side, but be quick about it, as four wart hogs have been released and they can get into the crawl space with you. When they're all bacon, pick up the revolver ammo, activate the jump switch in the E wall and go back the way you came through the N crawl space. Continue until you're back at the front side of the caged area and return to the main room.

You can see the raised block ahead, but let's save that for later. Instead, turn to your right and use Guinevere's Jewel to open the door in the N wall. Step inside and watch the ensuing flyby. Draw weapons and dispatch a half dozen jackals that come at you from all sides of the central pool. Jump into the water and swim into the N passage. Go past a closed gate and into a subterranean room. Pull down the ceiling switch near the E wall and swim back to find that the gate in the passage is now open. Swim inside the side passage (after getting some air at the main pool) and follow to a new green-tinted room.

Pull out onto the ledge and note that there's a stone block in each corner of the room. Visit them all and push each block twice to reveal an alcove containing a vase. Shoot all four vases, and when you've shot the fourth one you hear the sound of a door opening. Jump back into the water and pull down the ceiling switch in the center of the room. Pull back out to find a raised block at the S wall. Climb up onto it and pull up W onto a higher ledge. Jump to the adjacent ledge and enter the alcove in the W wall. The wall switch there is timed, and it opens the gate across the room in the E wall. Getting there is a snap, however. Simply reverse roll, come out of the alcove running and jump after the second step to the central block. Without stopping, jump across to the ledge in the E wall and enter the timed gateway.

Shoot three bats and step up to the raised ledge. Take a running jump E and grab the jump switch. It helps to keep the up arrow key depressed. If you miss, simply do what's described below and repeat. You'll drop down onto a slope. Slide down and grab the edge. Take a rolling back flip and grab the ladder. Climb back up. The timed gate is once again open, so exit this room and see that the central block has lowered. Take a standing jump down to the lowered block and pick up the ARTUS EFFIGY. You get a warning burst of music and you feel a slight shaking. Take the hint and back flip to safety. Spikes are supposed to shoot out from the block, but nothing happened in my case.

Jump into the water, swim down into the SW hole and follow the checkered passage back to an intersection. Turn right into the fountain room and pull out onto the ledge. Locate the ladder near the NW corner that was spike-protected last time you were here. Climb the ladder to an upper ledge and turn to face E. Take a running jump and grab the rope on the left. Climb up to stop Lara from swinging, slide to the bottom and inch slightly up the rope to dampen Lara's momentum a bit, then turn about 45 degrees to your right, swing forward and jump off to grab the second rope (just above the spikes). Turn slightly left to face the vertical E marble pillar, then aim just to the right of the pillar to land on a small ledge against the E wall. Face N and take a running jump slightly NE, curving to the right in midair so that you land safely in the opening in the E wall.

Follow the passage to a wall switch. Pull it down to open a trap door and release two blade balls behind you. Turn around and crawl underneath the blade balls. The spikes on the block in the center of the pool have disappeared, so get down, climb the NW ladder once more and jump to the first rope. Slide to the bottom, inch up a bit, swing toward the block and jump off to land cleanly on it. Pick up the ARTUS SCEPTER and jump into the water. Pull out E and exit SE to the room with pillars.

Locate the raised block near the SE corner and climb up onto it. Pull up E onto an outdoor ledge. Look down N and see the basket hanging from the E wall. You should have the grenade gun in your inventory, so draw it and fire a grenade at the basket. It loosens its grip on the wall and swings around in place. Safety drop from here and locate the crawl space in the E wall that the basket was blocking before. Pull up inside and crawl along the passage until you're able to stand up. Pull down the wall switch and return to the previous room. Another block has been raised near the NE corner (for later).

Run across to the dark SW corner and locate the ladder. Jump up to grab the ladder, climb up one rung and take a rolling back flip to grab the crawl space in the S wall. Pull inside, crawl forward and lower Lara down the other side. Climb down the long ladder and turn left when you reach the floor. Draw your pistols, stoop down and shoot the crate on the other side of the crawl space. Crawl into a passage guarded by a series of swinging blades. Time runs past the blades (note the closed gate in the alcove to the right of the second one) and grab the revolver ammo in the alcove to the left of the third one. Shoot several bats as you enter the next room, then shoot out the windows in the S wall. Hang from the edge of the opening in the floor and drop down onto a block in the lava room below. Hop N, then E, then N again, and activate the jump switch in the N wall. This attracts a fire wraith, so quickly reverse roll, hop back the way you came, pull up to the room above and jump up into the S opening. Hop forward into the water to extinguish the wraith. You can swim up N to investigate, but all you'll find is a closed gate in the upper wall.

Pull out onto the ledge and jump back to the opening. Hop down into the previous room and exit to the swinging blade passage. That door in the N alcove is open now, so go there and follow the passage to an open area over more lava. Don't run out onto the leaf cover, or you'll fall through. Note the mounted lion's head on the W wall. Beneath it is a plinth. Shoot the gem in the lion's mouth. Nothing seems to happen, so go back along the passage, turn right into the swinging blade passage and return to the room with the lava basement. Hop back into the S opening and jump into the water. The gate high up in the NW corner is now open, so swim inside. Two crocodiles greet you in the next room as the gate swings shut behind you. Swim forward along the floor and enter the small semicircular opening in the N wall. Swim inside and turn either right or left at the intersection. Pull down the ceiling switch in the next room, then swim to the companion room at the other end and pull down the ceiling switch there. Swim out and up, get some air at the hole in the center of the ceiling, pause for two stashes of shotgun ammo on the ledge at opposite corners of the room if you wish, swim down and exit through the now-open S gateway.

Pull up onto the ledge, exact your revenge upon the pesky crocodiles, and jump back to the N opening. Exit to the swinging blades passage, turn left into the alcove at the second blade and follow the passage to the leaf-covered area. A block has risen there, so jump to it, and from there to the plinth. Pick up GUINEVERE'S JEWEL and take a running jump back to the block and from there a standing jump into the passage. Turn left into the swinging blade passage, go through the crawl space at the other end and climb back up the ladder. Follow the upper crawl space to the room with the pillars and the raised blocks. Use the SE raised block once more to pull up E into a higher area and note the nearby closed gate if you didn't see it earlier. Run to the W end of this ledge and use Guinevere's Jewel in the receptacle to your left.

The door opens, but before stepping inside note two boulders suspended overhead in the ceiling. You won't trigger them until you start running down the ramp, so do that and jump over the lava trench near the bottom. You're still not safe from the boulders, so scoot to your left and continue running down the S ramp. You'll trigger another boulder, but you'll be safe if you jump over the lava trench into the SW alcove. Save your game and take a curved running jump NE to the ledge. Don't stop there, however, as the ledge is spike trapped. Hop forward into the E opening (you don't have time to pull up).

As you step forward into a room with a blue floor, a cut scene shows two ahmets being released to your right. However, you can still move freely, so draw weapons and kill them without waiting for the cut scene to end. Locate the flares in the NW corner, then enter the ahmets' dark lair, light a flare and locate the jump switch. Activate it to open the gate in the N wall outside. Save your game before entering and you should be able to complete the following task in one go if you know beforehand what to do. Run inside to trigger some flame blowers and rolling boulders. Turn to your right and wait a split second for the first boulder to roll by. Jump over the first flame blower before the flames become operative, then simply run forward to escape the second boulder and flame blower. The gate slams shut behind you as you enter the next room.

Pick up the revolver ammo at your feet as you see the gates to your right opening and closing seemingly at random. Your task is to shoot the vases that are exposed while the gates are open. After you've done that, turn and climb the center of the N wall. Pull up into the open gateway and pick up the ORNATE HANDLE. Drop down to find that the NW gate is now open. Take a running jump and grab the N wall. Climb up to the opening leading outdoors. Drop down through the hole in the ledge onto the raised block. Hop down to the floor and cross the room to climb the NE block. Pull up W and run to the other end of the ledge. Combine the Artus Effigy and the Ornate Handle to form the PORTAL GUARDIAN, and insert it in the device around the corner to open the nearby iron door.

Go inside and up the stairs. Shoot the ahmet that comes down to greet you. At the top of the stairs, pull out through the open gateway onto a high ledge as the camera angle changes. Take a running jump N and grab the edge of the roof. Shimmy to the left, around two corners, pull up and take a rolling back flip to the facing roof. Grab the edge, shimmy to the left around two corners once more, then pull up and back flip to the ledge. Turn around, walk to the far end of the ledge, face NE and take a standing jump into the opening. Camera control is restored as you slide down into the next room.

Run N and turn right into the blue passage. Shoot the crate (the vase is empty) and step into the alcove to pick up a large medipack in front of the closed gate while a skeleton tries to sneak up on you from behind. Monika indicates in her outline that this is a secret area, but nothing registered here for me. Note the hard-to-see jewel receptacle and exit this room. Enter the wooded area N, loop around to the right and locate the GATE KEY and shotgun ammo in the SE alcove. A fire wraith is awakened, so get out quickly, loop around to the right again and climb the E rocks to douse the wraith in a pool of water. Find GUINEVERE'S JEWEL in the water, go back down to the blue passage and insert the jewel in the receptacle to open the nearby gate. Hop down into the passage and jump over the circular tile, which is a spike trap.

Locate the wall switch at the end of the dark N passage and pull it down. Go back, jump over the spike trap (using the action key so Lara won't bump her head) and return to the wooded area. The W gate is now open, so slide down the bank and enter a small enclosed area. If this is supposed to be a puzzle area, it's a pretty simple one. What I did was to pull down each of four wall switches by following my nose as each gate was opened, ignoring any closing gates along the way. After pulling the fourth switch, I went back and pulled the first one back up, turned around and pulled down a fifth switch directly behind me, and now the way was clear to the open exit gate in the W wall.

As you enter, a brief flyby shows you a large lava cave with a number of pillars. Take a running jump and grab to the W pillar dead ahead. Pull up and make your way from pillar to pillar in a counterclockwise direction until you reach the one in the SE corner. From there, take a standing jump E and grab the opening. Pull up as the camera angle changes and pick up GUINEVERE'S SCEPTER. Reverse roll, simply run out of the alcove and you'll land safely on the previous pillar. Retrace your steps (don't try any short cuts, it's too risky) and now make your way to the NW pillar. Take a running jump to land in the N opening. Enter the next room and insert the Artus Scepter in the receptacle.

Jump back to the previous pillar and make your way to the SW pillar. Take a running jump S and grab the opening. Pull up, enter the next room and insert Guinevere's Scepter in the receptacle. Jump back to the previous pillar, pull up and take a standing jump NW to the next pillar. Climb down the ladder in the W face and back flip near the bottom into an open doorway. Go down the steps and loop around to the right to alert a jackal. Go to the other side of the room and use the Gate Key to open the S gate. Head down the passage and you'll come to a level jump.

Level 2: THE GRAIL

Run forward into the large open-air courtyard and watch the ensuing flyby. When camera control is restored, run forward around the tall central structure and jump into the pool. If you wish, you can engage a pair of pteranodons now, or you can wait until you return to the pool after the upcoming task. Swim into the SW opening and pull out inside a fenced area. Locate the revolver ammo in one of two holes in the floor, then get out and run to the E side as a swarm of locusts pursues you. Activate the jump switch in the S wall near the SE corner, then return to the W water hole and swim back to the pool. Locate the open gateway in the N wall and swim up into another fenced area. Pull up onto the base of the marble ramp, turn to face W and back flip to the slope behind you. Jump off to grab the ceiling, then monkey swing to the W wall and release to activate the jump switch. As you fall, the spikes retract in the hole below, so pick up the revolver ammo, climb up and go to the other side of the marble structure. Pull up, turn around to face E and repeat what you did earlier. After you activate the second jump switch, return to the water hole and swim back to the pool.

Pull out, return to the courtyard and locate the mounted lion's head high up in the E wall. Shoot the gem in its mouth, jump back into the pool and swim through the S gateway into the fenced area on that side. Pull out and locate the open doorway in the S wall. Note also that blocks have been raised to fill in the two holes in the floor. Enter the S passage and pull out the stone block. Place it on one of the raised blocks (it doesn't matter which one), then find another stone block in the passage and place it on the other raised block. A cage is raised against the E wall. Enter the S passage one last time and pull down the wall switch to raise another cage next to the first one. Use the cages to climb up to pull up W. Save your game in anticipation of an obvious boulder trap ahead.

The easy way to beat the trap is to run forward a short distance until the three boulders are triggered, then reverse roll and run off the ledge at the far right (SE) corner to land on the lower cage. Reverse roll, hop down and run forward to escape the boulders as they drop down to the floor. When they've all come to rest, vault up onto the pillar support and side flip over the boulders, climb back up the cages and proceed. Run up the boulder slope and you'll find a GATE KEY in the right corner. Picking it up attracts a swarm of locusts. Go back down, jump into the water hole, swim back to the pool and pull out E. Run up the ramp next to the central structure in the courtyard and use the Gate Key to open the gate. Continue up the ramp and you'll attract a pair of fire wraiths. Go back a bit and jump into the pool to douse them. Pull out of the pool and return to the ramp.

At the top, take the object of your quest, the HOLY GRAIL, from the plinth as ethereal music plays. Draw your revolver and shoot the white vases in the distance W. Go back down the ramp and jump into the pool. Swim into the N gateway and pull up into the fenced area. The iron door in the N wall is now open, so enter for a word of congratulations in German, slide down the slope and finish the level.
