Ragnar

Ragnar is a solemn ranger who could be found in Buccaneer's Den during Ultima IV.

Description
Ragnar travelled the realm of Britannia, and knew of a great many things as a result. Should the Stranger, following a tip from Sebastian in Britain, ask after the Skull of Mondain at the Captain Black Tavern, the hero would eventually encounter Ragnar, who would warn them that if they ever used the skull except to destroy it, all of their virtues would be lost.

Trivia

 * A "Ragnar the Rugged" appears in the Ultima III cluebook Secrets of Sosaria, where he is listed as the individual who explored and mapped Dardin's Pit. Given that many of the other characters in this publication are taken from the personae of Richard Garriott's friends in the Society for Creative Anachronism, it is possible that a real world individual lent his SCA-name to this character.
 * In the Nintendo port of Ultima IV, an unnamed pirate appears in Ragnar's stead, warning the hero against retrieving the Skull, but nevertheless directing them to its location east of Serpent's Hold.
