Shanklick, from Ultima Underworld
After hearing rumours in Ultima Underworld that someone named Shanklick had important information about the mad wizard Tyball, the Avatar found her in the fifth level, acting as the leader of the Exiles of the Abyss.
Shanklick had a problem solving a murder among the Exiles. The Avatar suggested that she feign sympathy with the murderer and offer a reward. Shanklick liked the Avatar's shrewdness, and said that Arial had been brought to Tyball in the levels below them, revealing the location of the stairs down in the process.
