In the middle of this room is . . . a knife, with a copper hilt and a very sharp blade. There is also a small pit; it smells vile and acidic. Dropping the knife into the pit just makes the knife reappear on the floor. The knife cannot leave the room.

You are aware that when you pick up the knife, you will experience a drilling headache, and feel like your memories of Aather and what came before it are being sucked out of your head – they're not actually being taken, but they feel like they're blurring, spotty, utterly uncertain, eroding . . . it is an extremely unpleasant experience, which will last the rest of the game.

Only one person may do this task.
