Aster's minor in mythology brought him to plenty of places to study. And his interest in curses and convenient lycanthropy makes acquiring and removing curses fairly easy.

Who would have thought a harpy's egg would have such a transformative effect? When consumed the person can say they feel light as a feather and can sing beautifully. In some cases they can have an unlimited supply of eggs.

Aster learned the hard way what some yolk on his face can do, and he had to quickly find another egg to make an antidote before he went a little bird brained.
