My name is Jupiter

It's been the most interesting thing.
I spent my days living in what I believe was one dimension.
I'm still unclear if this is the same one.
Everything seems familiar.
Like I have been here before.
So maybe I have always existed here.The only things I am certain are absolutes?
1. I'm Jupiter Rose.
2. I own a shop in a space called NetherVille.
3. There are other spaces beyond the walls I have yet to visit.
4. There are more than four walls here.
