Eiko

Eiko is a young woman on a quest for vengeance with her half-sister, Amanda, during the time of Ultima VII.

Description
Daughter of the mage, Kalideth, Eiko lost her father when he attacked the cyclops,  Iskander Ironheart, during his explorations into the disruption of the ethereal waves. The mage, driven insane by the polluted ether, had assaulted the cyclops without provocation, and unbeknownst to his daughters, was killed in self defense.

Meeting with her previously unknown half-sister, Amanda, after Kalideth was slain, Eiko committed herself to the task of vengeance and studied under Karenna of Minoc, in preparation for their quest.

The Avatar could encounter the two sisters in the midst of the Dungeon Deceit, where they were close to discovering the cyclops. Should the hero find Iskander before them, however, and uncover the truth of Kalideth's end, they could plead with the sisters to abandon their quest. Thus informed, Eiko would readily abandon her pursuit of Iskander, and would convince Amanda to do likewise.

Trivia

 * In the face of grief at their father's death, Amanda and Eiko had considered joining the Fellowship in the hopes of gaining direction from their philosophy, although they had not committed to such an action at the time the Avatar met them.
