Siona

Siona is the court musican of Castle Britannia during the time of Ultima IX.

When the Avatar first met her, she explained the differences between a piano and a harpsichord. She also gave a demonstration of Stones on it from memory, not needing any notes anymore.

Later, after returning with the need to find the Ankh of Spirituality, the Avatar again met her. Siona by then had written Stones as a music sheet, and glad gave it to the hero. The Avatar used it with the harpsichord in Lord British's room to make the ankh appear.
