Thought I'd do this as well. Big, barrel-chested, foul mouthed Iggy. He's the brother of Xerathogus, who is the late father of Pyrothraxus and Zestos. So, no, he's not related by blood to Malystryx, thank goodness. Which is why he berates her every chance he gets. She was the one who killed Xerathogus when he wore out his usefulness to her. He didn't like the idea of Malystryx killing off his favorite little brother. But Iggy allows her to live to torment her with the idea that one day he may kill her. Apparently, the meaning of family runs deep in Jonathan's father side.
Ignatius is in fact a Latin word, meaning fire.
