Rowena

Rowena is the dead wife of Trent, the blacksmith of Skara Brae.

Horance had some kind of desire for her, so after he had risen the dead, he ordered them to bring Rowena to him. However, the dead were real clumsy and accidently killed her in the process. Horance didn't care, since he could have her ghost anyway. So her soul stayed as a prisoner at his side.

Only during Ultima VII was she finally rescued. First the Avatar played her husband's music box near her to give her a short moment of clarity, allowing her to give him/her her wedding ring as a sign for her husband that she was well (as far as possible for a ghost), so that he could finish the Soul Cage. Later, after the Liche was destroyed, the Avatar returned her to Trent. She and Trent after that never wanted to part again.

So it was only consequential that she denied the final sacrifice. When the Well of Souls was later destroyed, her soul escaped to the void, finally at peace.
