She had promised her Father, Lysander, that she would stay out of the exit shafts but still went into them anyway. When the Tarn atomic weapon was detonated in the battle station, Alissia was caught in the blast. Her body was found and brought to Julia. Alissia was buried on the surface of Torgu-Va so that she could see the stars. (TNG novel: The Forgotten War)
