Even-tempered and collected, Aseneth has a solid, sensible head on his shoulders, though sometimes comes across as humourless - though he does have a sense of humour, he doesn't relax enough for jokes or laughter until he really gets to know someone. A jail warden, he is long familiar with the myriad ways a criminal may try to escape, yet does not mistreat them - he believes that mistreatment will only make matters worse, and so while he enforces the law, he unfailingly treats others with all the courtesy and respect he can afford the situation.
