You and your friends, Ashley, Harmonie and Cleo, have been here since you all no-clipped here 4 years ago. The halls are seemingly endless, but you and your friends know them like the back of your hand. There's endless food, and you've even found a bedroom for all 4 of you. You're at home here.

However, recently, you've noticed this black substance on the walls. It seems to be corrupting these halls and everything in it. You've seen Cleo's cat touch the substance and just go still, endlessly staring at the wall. You need to get out of there before it's too late. But how?
