My character would still be happily torturing dwarves for Empress Jengu if he weren't marked.
He might try to find some purpose in his life by seeing it as his duty to find out what the hell went wrong and report back to her somehow, though... Hmm... (He's going to be a very pedantic person who likes routine, and will be thrown WAY out of his comfort zone by being compelled to leave his comfy job back home and trek across the world to an uncertain fate).
Hmm... maybe I should RP him like House... (a complete asshole, but insanely perceptive and very knowledgeable). Also, I could totally see House torturing people and not feeling bad about it at all, if that was part of his job description.
