Deity of Human Origin

A Deity of Human Origin is an actual god created by humans (or other mortal beings), or who used to be one such mortal being (or several) before becoming a god. Not merely godlike, but an actual de facto god who has created a universe or sentient species or performed some other feat worthy of a true god. May or may not still have a physical body. The mere fact that the universe existed before this character's ascension implies that there are primary gods who have given a large part of them into shaping the universe and that this creature is most likely one of the secondary gods.
