Mnemon Gia’senai is a great-granddaugter of the Scarlet Empress decended from Rulinsei, a younger sister of Mnemon adopted into House Mnemon. She had a fairly wild and wide-ranging youth after graduating the strict confines of the Cloister of Wisdom. He exploits in the Threshold earned her a name, and the military experience to hold a position of command in the House Legions despite her relative youth.

She has dark skin, almost shale-gray, and light blue-tinged unruly hair, which she keeps cropped shot. She commonly wears her armor and command cloak in public, but ditches the frills of command on the battlefield.
