Daranor

Daranor is an insane man who may be found raving in shrubbery of Moonglow during Ultima IV.

Description
Daranor appeared to be afflicted with some manner of madness, claiming that he was responsible for the motion of the sun. Seemingly unaware of his own well-being outside of his celestial mandate, he claimed that the twin moons of Britannia opposed his cosmic works, and begged the Stranger to help him in dragging the malevolent satellites from the sky, denouncing the adventurer as a fool should they refuse.

Trivia

 * While Daranor is almost undoubtedly insane (evidenced by the fact that the sun appears to remain stable long after he presumably dies), his madness does reflect the geocentric model that is generally accepted by Britannian astronomers. Interestingly, workings of magic eventually do drive the moons to nearly fall from the sky in Ultima IX.
 * In Yoko Tanaka's manga re-telling of Ultima IV, Daranor is the dwarfish and deformed-looking henchman of the malevolent Hawkwind, who is eventually responsible for the death of the protagonist's brother,  Shiva, before being killed by  Shamino and  Mariah.
