@Moodyz It was his role among the demons. He basically lived his life hearing he's useless because he couldn't use magic. Demons incapable of using magic are trash, after all. So, his only worth was to serve others, whom he thought far superior to him, the best he could. His current attitude was probably what was expected from him among the demons.
@Robbini Any Skyrim player who wants to level up smithing and enchanting... Before selling them, at least.
@Riger Nah, you can refuse a duel, and that's it. Nothing would happen. The MC accepted it by picking up the glove, however. After that you have to fight or lose by default. Claiming all the possessions is a bit much, however. Duels are about honour and pride, not about robbing people.
