Also, I like how you had an SC agent go rogue. Just remember, he won't be a completely different person, and he probably won't be hostile to The Culture. He should still have, for the most part, the same goals. But if he was made Orky, he'll be more interested in winning and strength and cunning and violent and extreme types of fun and using a direct means to do things. But the actual goals and viewpoints, otherwise shouldn't change too much.
