I'm not picky about length as long as you get the point across.
I encourage there being romance, and will allow 18+ things, but if sex becomes the focus of the whole roleplay, I'm out.

basically, my oc is an artificial human, powered by magic. said being is created as a surprise gift for your character, who has been alone for a while. this being is built to act human, but is somehow exposed to chaos magic, ending up causing her to develop a soul, and truly BE human, leaving you with the question of what to do.
