Pokémon
Here's some basic rules for the world.
Kanto and Johto are fused together.
Each Region has Deities (Legendary Pokemon) that govern over and guard that region.
All Pokemon can talk to each other, but not to humans.
my face when I realize I have over 100 Pokemon OCs 
^ these are buttons to filter by type ^
The Distortion world is a real seperate from the regions, but it seems to have a connection to Sinnoh. It is a land where the rules don't make sense, physics are non-existant, and Ghost-types rule.
