Mordra

Mordra is the dead healer of Skara Brae in Ultima VII, where she is essential help for the Avatar. But she is far more than she appears at first, because she actually is from Pagan, and the grandmother of Vardion, the First Acolyte of the Sorcerers.

Her history is a bit difficult to reconstruct. Some time after Ultima VI, Mordra and her brother Rinaldo left Pagan and entered Britannia, probably because they were unhappy with their lives there. Mordra became the healer in Skara Brae, but visited Vardion still from time to time, to tell him of Britannia. When Horance became a threat, it was her who found the mixture to destroy him. But the mayor gave the wrong quantities to Caine, resulting in her and all of Skara Brae dying in a huge fire.

In Ultima VII, she was a ghost, but was able to communicate with the Avatar even without the Seance spell, and was the only one remembering the Dark Service of Horance at midnight. She gave him/her much good advice about the inhabitants and the events and, when asked, the correct formula. The Liche was destroyed, but Mordra was unable to do the final sacrifice, since her powers from Pagan would have caused huge destruction then. With the Well of Souls destroyed, her soul escaped to the void, finally at peace.

Trivia

 * Her full name, seen in a book, is "Mordra Morgaelin". What a coincidence, that Morgaelin is the only known isle in Pagan...
 * Vardion mentions Mordra in Ultima VIII. It becomes clear, that she had been a Sorceress, but Ultima VII proves, she found the path of Virtue. Sadly, the Avatar doesn't tell him of her fate.
 * Mordra is also mentioned in "The Chronicle of Pagan".
 * Fitting that a Sorceress died in a fire...
 * She mentions her brother, Rinaldo, working in the High Court in Yew, but Rinaldo isn't seen there. Either he has moved on or died but it seems likely that Mordra would've known about his passing.
