Ishtass

Ishtass is a grey lizard man found on the third level of The Abyss.

When the Avatar met him in Ultima Underworld I, the hero was surprised that Ishtass was capable of speaking English, although he admitted that he had to concentrate for it. This had made him an outcast from his differently-colored brethren, and Ishtass couldn't offer much help with lizard man vocabulary, as it went against certain oaths.

He could, however, tell the Avatar much about their history, and revealed that he was searching for a scroll once possessed by the great Ossikka. Upon acquiring the scroll for him, Ishtass gave the Avatar the only WIS-Rune Stone available in the Abyss. He also revealed the fate of the sword Caliburn and where to find one of its pieces.

When the Abyss was later destroyed, he went deeper underground, as did the other lizard men.
