I Branch
Th worlds in this branch seem to live in a kind of mindscape. Everything is shaped by the mind, by thoughts, and many live inside their heads. Nightmares and dreams exist in both dreamland and reality here.
IU1 is a world who's population is mostly, if not entirely, dream religious. These people believe that the highest form of enlightenment is that of dreams, and to spend your life in them is to be "born" into reality. To them, reality is a dream and dreams are reality.
Do not visit this world unless you want to be driven insane. Everything here is made of thought and dreams, and can crumble or building in miliseconds.
