Old One
this was the name given to the Force-sensitive individual who lived in the Onacra village on Aduba-3, many decades before the Battle of Yavin. It was the Old One who discovered the existence of the Behemoth, deep beneath the planet's surface, and was able to bring the creatyure out of suspended animation. The Old One was unable to control the Behemoth, and was trampled to death when it managed to break free.
