In the mirror universe, T'Pas was a Vulcan slave, "acquired" by the Romulan businessman Rojan in his youth. T'Pas died giving birth to Rojan's daughter, Soleta. Like many Vulcans, T'Pas had telepathic abilities, which she hid from others (including Rojan), but were passed on to her daughter. Rojan hid the true identity of Soleta's mother from others. (NF - Mirror Universe novel: Cutting Ties) Although Soleta's Vulcan mother was not named, it can be assumed that she was the mirror counterpart of T'Pas, Soleta's mother in our universe.
