Marya the Ageless
A legendary human sorceress who was said to have uncovered the secret of immortality. She is credited with the invention of the Soul Gem spell.
Most of her deeds have passed on into legend after her disappearance during the reign of the The Red Tyrant. Apparently she was even then hundreds of years old, but looked to have been in her thirties.
Marya finally found the peaceful rest of death during the ritual that defeated the Dog of War’s undead army.
