If you had watched from the beginning *sass*, then you would know that Aphmau spawned in the world as a human character that slowly became a part of the world. It's also hinted in the diary of the old Lord of Phoenix Drop that he might has also been a human as his first entry was talking about how NPCs in this world are different.
