Isu is a Human dimensionalist originally from the town of Telles on the island of Leffotin. She traveled with her parents quite a bit when she was young, even visiting Sigil for a while when her father worked at one of the City of Doors' eating establishments. It was there that she developed an interest in the school of dimension, and also learned the arts of fortune telling.
When she showed talent in magic, her parents sent her to Rogariel to attend the University Al Maneera. There, she met her two best friends, Zaikum and Ikuyan. The three of them have met every year since graduation in Agropthos -- Zaikum's home town -- for the festival of the Day of Change.
Isu is a PC played by John Proulx.
