Aria

Aria is a pirate who, together with her partner-in-crime Dunstan, abducted the Silver Serpent from the Cathedral of Love in Ultima IX.

The Avatar was first put on her trail when the female monk Kimberly told the hero of the theft of the Serpent by Aria, who's posed as a monk to gain access to the serpent, then stole it and looted the Serpentwyne cache of the cathedral. After arriving on Buccaneer's Den, it didn't take long to find the hideout, where Aria and Dunstan were arguing what to do next. They were surprised and killed by the Avatar in the following battle.

It was later revealed after freeing the Serpent, that the Guild of Buccaneer's Den was behind the crime.
