I have a character concept. Basically a barbarian warlord, but also a master of monsters and manbeasts and such. He believes himself to be the reincarnation of "the Wyrm," the destruction-god of his druidic religion, and has taken it upon himself to scour the world of civilization so that it may be cleansed and reborn anew. Likely he sees Kil'threx as being an avatar of Gaea (the queen deity of his religion), under the aspect of the Wyrm.

Here's the real kicker though; he's called the Dragon King, and is the sacred leader of all skin-changers. He's the last true Weredragon.
