Maxine Ming is a princess from the Principality of Kesh. After she was recognized as a Stratus, she was sent to study at the September Institute.
As is custom on Kesh, she has covered hair and "dresses like a pilgrim" with long skirts and such. She is apparently "cool as fuck" and never seems out of place despite her unusual appearance.
During the September Incident, she encountered Cassander while they were being affected by the memory-altering powers of Voice, giving the two of them implanted memories of time as colleagues in House White Star studying at the September Institute. Although they eventually realized these events did not actually occur, she and Cass remained platonic friends, prompting them to rescue her with the Apokine as Mode City was consumed by a wormhole.
