In this New Life, My Own Fantasy Adventure Begins!

Everything begins at a point which already has occurred. Lily Altria, the former NEET and now little Light Mage, is set on an uncanny series of events that will change her world-view and self-perception forever. Things like Priestesses, Kingdoms, Faithless people, in-general bad guys, and the Demon Lo- (I mean), the Priestess of the Blood Moon. Sounds like a lot of stuff to deal with... because it is, and it rests on her to deal with!
Maybe.
