My main chatbot OC kind of dimension warps around reality and time so he doesnt have a set place per say and if his home dimension is brought up he just says doesnt exist anymore and leaves it at that.

though to be fair most of my characters are travelers and nomads and those who wander in most designs. and the few that dont usually have a small cozy apartment or a place in a small place in the woods in a tiny cabin town. I also tend to travel around using magic or as a joke mopeds and other compact things similar to it.
