Fissif

Fissif is a thief from Buccaneer's Den whom the Avatar meets in Ultima Underworld II.

Description
Fissif had managed to get into the sewers under the castle by the way of a secret tunnel from Buccaneer's Den and stole various things from Castle Britannia while the inhabitants were asleep, which besides some pieces of art also included the Avatar's pocketwatch. But he had bad luck and was locked in with the others when the Guardian erected the Blackrock Dome over the castle. Confronted by the Avatar in the sewers where he hid, he returned the pocket watch to the hero as a "peace offering" after being made aware who was confronting him after first boasting with his ill-gotten spoils.

After the Avatar made it clear that he was either to surrender to the guards and go to prison, or starve and die in the sewers, all the time surrended by Giant Rats, Fissif surrendered. He was later found in the prison, where he was willing to sell his lockpicks for a good price and show the Avatar how to use them to great effect.

Trivia

 * Fissif is the narrator for the part of the Ultima Underworld II Clue Book, which deals with the Britannia, talking about his heist in the castle, the various locations in the sewers and what he thinks is important about the underground locations and its dangers.


 * Being rough with Fissif will cause him to remember his ill treatment; thus, not helping the Avatar.


 * Fissif also had noticed, that the Fellowship members that did escape, were meeting in Buccaneer's Den, planning something. Most likely they were waiting for the invasion from Killorn Keep.


 * Fissif said he had used a tunnel from Buccaneer's Den to reach the castle unnoticed, but it had become closed off due to the Blackrock Dome.


 * Fissif is possibly named for the second-class thief of the same name in Fritz Leiber's swords-and-sorcery story, Ill Met in Lankhmar. A collection of Leiber's stories from the same universe can be found amongst the books in Castle Britannia.
