A small cafe that sits... well, almost everywhere. It's an inter-dimensional building that sits in many places at once. Some people think it exists in the void between worlds, connected to all these different places via some strange magic that people are unaware of.
Run by a young person by the name of Rhen Winchester, who is extremely welcoming and amicable. This cafe can be a cesspool of different people from different places, including supernatural people or creatures. Rhen is welcoming of all people and all genders.
The cafe has a supernatural air about it. It is a lot bigger than it may seem, and some worlds and places may bleed into the cafe. One never truly exits, unless by the front doors. But how did that lake get here? Was that tower always there? Pretty sure there's not supposed to be a dragon burning down the tables and chairs, maybe someone should stop that.
This is basically going to be an open-world meeting place for people of all different worlds and creations. In case you have that character you want to develop, but there's not really a world for them, or you don't want to introduce a world of your own.
