John Gattoh is a member of the Brotherhood of the Force. An Acolyte for the Brotherhood, he is a prominent field commander. John is consider a Sentinel or someone that is tasked to hunt down "miss users" or rather Dark Jedi and Sith. He is one of many field commanders that runs a Sentinel operation and is mostly tasked to the Corellian Trade Spine region, which is the most dangerous region in the Galaxy for Dark Force activity. Surprisingly, John has not taken an Apprentice like most Acolytes do in the Brotherhood.
