Ozza [d. 174 BG) was a slave woman on Poritrin. She became the wife of Ishmael and with him had two daughters, Chamal and Falina.
Ozza saw her husband removed from his family as a punishment for his audacity to meet Lord Niko Bludd personally. It was the last time she saw him, and was taken to work for Norma Cenva. Some years later Chamal as well was removed, and Ozza remained only with little Falina.
Mother and daughter most likely perished during the retaliation for the second slave revolt of Poritrin, started by Aliid. Ishmael, had escaped to Arrakis, and after consuming melange, saw a vision of them killed slowly by knifes.
