I probably should have done this earlier....
WHAT IS A LIMINAL SPACE
Okay so you know the multiverse theory? Where there's infinite universes where anything could be true: Spiderman is real, everyone is genderswapped, Britain won the Revolution, fish on pizza is normal, etc. Well it's true! (Acording my boss: Legally, this is a roleplay account do not believe this 20 year old) And sometimes things move a little wrong and a little pocket is created and well....
That's where shit doesn't follow the concepts of earth.
Alternate realities often follow the most of the commons of earth. Such as locations, planets, people, or gravity. Realities often aren't to far in difference.
Liminal Spaces....those pocket dimensions feel familiar but....it's very different/wrong. The definition of uncanny valley imo. They are often small even if infinite....and often deadly.
And they have there own laws.
