OC's World.
My OCs don't all live in the same world. WHere they all live is really arbitrarily thought actually. most of them just exist in some way, and some of them even know and hang out with eachother.

The Cat Trio and their associates, I know all of those ones live in the same kind of area. They know eachother, so they have to live in a place where its possible for them to meet. All those "Space animals" basically XD. But I have a lot of miscellanious OCs. Ones that know eachother from some places. OCs that never met before. OH and some that get plopped into DnD.

Multi-Dimensional OCs: https://ulurifox.wixsite.com/uluri/characters
Those would be my main OCs for the most part. Uluri, Trace, Sin, and Kindling. Uluri's house is in some vaccume of space house on a small floating island? Why? Because Uluri is an OC who needs to be able to go to many other places. Trace lives with Uluri to take care and babysit, but is in themselves an adventurer. Kindling Visits this place, but ultimately lives in his own house in another place nearby a village of some sort. It was once an abandoned house. Sin... well he started in DnD, but he weaseled his way to here and all sorts of other places as well.

My two other mains I list with those four, Zozo and Blizzard, they are in their world. They aren't multi-dimension traveling, but they are mains because I love them. All of my OCs can very well be pulled around with Uluri if I want, but they wouldn't be like Uluri.

Everyone has Pockets they live in. Not all of them cross, but they're all accessible through Uluri.
