King Jatizso was the founder of Jatizso, a Fremennik island. He was the brother of King Neitiznot, Neitiznot's namesake and founder; they were both exiled by the Fremennik people due to their feuds, which are still manifested in the feuds between native islanders. The current king of Jatizso, King Gjuki Sorvott IV, is descended from him.
