Ketcheval, from Ultima Underworld
The Avatar met him in Ultima Underworld I, after getting by his wife Retichall. Ketcheval had no information about the kidnapped Arial, complaining that he had other worries and lots of enemies surrounding them. Besides his feud with the green Goblins, he complained about a horrible wolf-spider named "Navrey Night-Eyes", mentioning that her web had special properties.
This information proved important, since this web was needed as the second component for the Dragonskin Boots. Ketcheval also spoke about how the Goblins had been invited by Sir Cabirus years ago and that his stupid dream had gotten them into their misery. He cursed the man for this.
