Isolde

Isolde was a druidess who appears briefly in the quest Kindred Spirits. She was a contemporary of the Barrows Brothers and was Guthan's lover. However, Ahrim deliberately sabotaged the relationship in order to "save his brother's soul", as he put it, because Ahrim viewed Isolde as an idolator (presumably for worshipping Guthix and not Saradomin). However, both Sliske and Guthan imply that the real reason may have been that Ahrim had feelings for Isolde herself.

During the quest, Sliske revives Isolde in front of Ahrim and Guthan, and Ahrim kills her, possibly for a second time (it is hinted that he may have killed her in the past as well).

Trivia

 * The subplot involving Isolde resembles a scene from Disney's The Hunchback of Notre Dame, with Ahrim's attitude toward Isolde mirroring Judge Claude Frollo's toward Esmeralda.
