That's a lot of information for Theo to take in and try to relate to. In the end he comes up with a very necromancery way of seeing it. The Princes are a kind of undead that require the Queens - who act as necromancers - to the princes. Blood necromancers, as he would call them, who were trained since birth to control these particular kind of undead. They're savage unthinking undead given thought by the Queens.

"That... actually gives me an idea that might be helpful in case you do go ... berserk," he says, "But, I'd have to try something before hand to see."
