Thieves

These criminals actually try everything to go out of the way of a direct confrontation. They prefer to steal from people when they won't notice, or break into houses when the owners are not at home. However, should a Thief be caught in the act, he will most likely run away rather than trying to defend himself with a weapon.

Thieves seek throughout the cities.

Lore
''Long before the coming of Mondain, the common cutpurse was a plague to travelersin Sosaria. Lurking in alleyways, poised behind trees, and skulking in dungeon corridors, these villains are always ready to relieve innocent citizens of their valuables and their lives. 'Tis a service to your fellow Sosarian to exterminate a Thief whenever possible.''

- from "The First Age of Darkness", Ultima I

''An ordinary human pickpocket, the thief would rather snitch than fight. Always check your inventory [Z] after being confronted by a thief.''

- from "The Second Age of Darkness", Ultima II

''These are the worst of the human trash that pollute the countryside. Thieves can steal any weapon or armour that thou hadst, except for those with which though art equipped.''

- from "The Book of Play", Ultima III

Notable examples

 * Stefano in Moonshade in Ultima VII/2 is a classical Thief, who got thrown into the Mountains of Freedom. Once escaped with the help of the Avatar, it's likely that he resumed his career in stealing.
