Gloom
Afflicted by severe amnesia, you drift deep into the Common Dream. You scour for the lost pages of the Necronomicon, while clinging on to any little purpose you have left. Faced with mad dreamers, horrible abominations and eldritch deities, you feel drawn to the dark Abyss deep within. With every death you face, you return back to the top layer of the Dream, starting all over again and losing a bit of yourself in the process.
