Isawa Tomo was a gifted young shugenja who became Master of Water at a very early age. Tomo had spent most of his life mesmerized by the waters near his home and across Rokugan, and coupled with the power of his abilities, his appointment to the Council of Five was inevitable. Tomo was a Master during the Clan War, and as a result died Tainted at the hands of his cousin Isawa Tsuke, like his fellow Masters.
