The "Crystal of Creativity" (TM) usually keeps "The Forge" from getting sucked into a black hole. 
But lately its energy level is frightingly low. 

Can you help Lara reactivate the Crystal of Creativity (TM)?

But you can fall to death, get bullied and sucked into black holes.

Side effects:
Vertigo, visual diabetis and confusion about the laws of gravitation and aspiration.
Over-analyze at your own risk.
