Justeaze Lizrich von Einzbern

Lizleihi Justica von Einzbern, known as the Saint of Winter, was a homunculus whose family desired the Holy Grail long before the Holy Grail Wars began. When their attempts continued to fail, the Einzbern reluctantly accepted the aid of the Tōsaka and Makiri (Matō) families and under the guidance of Zelretch, they formed the Holy Grail Wars. Justica agreed to form the core of the Holy Grail; as such, her descendants (Illyasviel von Einzbern and her mother, Irisviel) each contain within them parts of Justica's memories and personality as well as a genetic resemblance to her.
