"You know of Phyrios Mattimus, the exiled Duke of Deshaan? There's a rumor going on that he's having a love affair with a Dunmer commoner. And not just any commoner--a convicted thief who's being held in the Legion dungeons!" -> there's a Dunmer woman in the dungeon whom the Duke supposedly fancies, could be a social quest there. The thief stole something from the Duke’s chambers; the Duke caught her red-handed and fell in love at the same time. The thief’s in the dungeon cell, showered with fancy gifts. She isn’t into him.
