Backstory

There once was a little girl, who was completely normal, at least on the outside. She got average grades, had average looks, and an average family. But her mind was... Twisted. She was quiet, but only because she lived in her own mind, warping her reality to suit her desires, she'd pretend. And one night... One night it stopped being just pretend. As she heard her neighbors fighting, she pretending to herself that there was no one else in the world... And then there wasn't. Not realizing that she was, in fact, changing reality, she started doing more, and more. She created herself a little kingdom, benign at first. It was picture perfect- A tall, crystal castle, a quiet garden and a beautiful forest, with a little park for her to play in. But the solitude slowly drove the child insane. Her park warped itself, twisting and curving. Her forest started to bend, it's colors started to change. Her garden turned on itself, plants eating other plants and hiding from human sight. The castle shattered the laws of physics and reality, becoming something new.
And the little girl? Lost herself to her madness, somewhere within the castle walls. Perhaps she wanders them still, eyes wide and unseeing.... Or perhaps she is a skeleton, dried up and shriveled somewhere within. It matters not- the castle itself will never let anyone find what may remain of her, and none have outsmarted it yet.

People have started appearing into the realm, inside the throne room of the castle where she lost herself. Now forced to figure out this twisted land, the people themselves just may go as insane as she did... Or perhaps they'll adapt to it, and keep a grip on their minds. Only time will tell...
