I would totally read a comic about DJ trying to halt the decline of magic. He's doing the right thing for all the wrong reasons. He starts out mildly ethnocentric, believing that Callan is rightfully the most powerful country. He's a bit xenophobic and maybe he's worried that other countries will take advantage of Callan if they lose their magical prowess. But few other people believe him and are capable of helping him. And maybe the magic he's using starts to drive him insane, heightening his paranoia and he ends up believing that not only is it imperative that Callan keeps its magic, but that they should use it to subjugate the other countries - to help them, of course. Then he ends up taking over the country and becoming a tyrant.

It'd be a lot more interesting than Dominic, Paragon of Ultimate Morality, that's for sure.
