As I've observed a few times now, one of the issues at the heart of our would-be traitor Vrannus' villain origin story is that he's a femboy, which is at the exact opposite end of what's expected not only from a prince of Khor'minos but just an average everyday Southern Minotaur. Dude's got issues about it up the ass. (Which is funny because he likes taking it up the ass too.) Juvenile jokes aside, while it's probably too late to get him a summer job with a mining outfit to put some muscle on his bones owing to him being accustomed to being a lazy so-and-so, we could probably help him with his self-image problems if we were allowed to take him into our custody as a prisoner or spouse post-siege. I mean, with his naturally heart-shaped ass, complete with actual heart-shaped birthmark, long hair and the way he fills out that Jessica Rabbit dress-like toga, not only is he perfectly suit to sit beside us in court (on a smaller throne or at our feet on a chain, I leave that to your imaginations, friends) but a well-meaning, patient and kind Champion could probably help him feel comfortable in his own skin, get him jewellery and more dresses, hair decorations, help him understand it's okay to be girly in appearance as a male. Hell, considering the Frost Elves' gender dimorphism is much more blurred, he'd probably fit in more with them than his own people, not having to be built like a brick appartment block and all that.
Alternatively, while this wouldn't be my first choice, corrupt or Dark Knight Champions have bullying material on him for life, and could find all kinds of ways to mercilessly victimise him when they're not dragging him into the bedroom and making him feel/cum like a girl.
