Cleansing of Kashyyyk

In 3993 BBY, Jedi Knight Guun Han Saresh ventured to the Wookiee world of Kashyyyk to hunt a "great beast" that was rumored to reside in the planet's Shadowlands. During the Great Hunt, a collaborative Jedi effort to rid the galaxy of Sith-created monstrosities in the aftermath of the Great Sith War, Saresh had established himself as one of the very best hunters in the entire Jedi Order. As such, he was handpicked by the Jedi High Council for a secret mission to rid the Sith homeworld of Korriban of the vicious terentatek beast. However, Saresh left the group and instead went to hunt the rumored "great beast" of Kashyyyk, which he believed to be a terentatek. After setting a trap for the beast in the Shadowlands, Saresh attacked the terentatek with his Force-imbued blade—unfortunately for Saresh, the sword shattered on his prey's tough hide, and the defenseless Jedi was eaten alive.
