Part bat, part cat, all-Ionian Hero!
Everyone's favorite baggy-pantsed Chthonic Knight-in-training with his own portrait to match his friend Arpeggio.
Prosper is an Ionian from the realm of Ionia in the 13th Moon, a dark world under the oppressive rule of Lord Knight Mortulon of the Order of Knights Descendant. Prosper came to the desert world Moonwind as a potential squire to the Chthonic Knights, and as such generally carries out menial tasks for them.
Of course, to the rest of us, he's just a cute fun-loving guy :D
