Grand Sage Fung-Tun was a Jenaïst and the leader of the Zoraï people from 2504 to 2506JY.

In 2504JY he used his influence to exile Mabreka Cho and become Grand Sage after the death of Hoï-Cho. His reign was only two years long though; in 2506JY he had become completely insane and ordered that Zora be closed off to all foreigners. Mabreka seeing this, returned from exile and deposed of Fung-Tun.

During his rule he established Jena as the Kami superior and unsuccessfully tried to convert the Fyros to Jenaïsm.
