Derydlus

Derydlus is a tavern patron in Moonglow in Ultima VI.

Description
Derydlus was a fun loving man who frequently visited the Blue Bottle Tavern to enjoy a bottle of Frasier's Folly. Mandrake had once told the Avatar that Derydlus could drink him under the table, and Derydlus certainly lived up to his reputation. He especially enjoyed drinking with his good buddy Manrel the alchemist. Derydlus highly recommended that the Avatar get his fortune told by Penumbra, firmly believing that she had a gift for telling the future.

The Ultima 6 Project
In The Ultima 6 Project, Derydlus mentioned that his friend Manrel had just buried his cousin Beyvin.
