I have ideas for at least 4 more characters, but I cant play more then one without getting overwhelmed. :(  Feel free to steal.

[b]Goddess Mnemosyne[/b] - Daughter/Son abilities: They can vividly remember everything. Every detail seen, every word heard, they can recall. They also can remember exactly how to do things after doing it once. Basically they have a god given Eidetic memory, and the ability to perfectly mimic, and replicate movements like a form of muscle memory.

[b]Goddess Hecate[/b] - Son/Daughter abilities: Sorcery and witchcraft!
