Daecon's father Darion killed his own father, tried to kill Daecon, killed Daecon's lover Evander (but Daecon brought him back), and killed Daecon's other father Dionysius, so he's kind of a prick...
Even worse, though, is Harmachis. He committed genocide and in the Defining Daecon universe is responsible for the extinction of satyrs, giants, and possibly vampires. He has also reduced werewolves, imps, hecates and fauns to critical levels (this genocide happened 5,000 years ago and the populations of these races have never recovered). Even his (and Daecon's) own race, the shapeshifters, has been on a path to extinction thanks to him.
It will be Daecon's job to right this wrong.
