Kohriak'gelic was a Kahnkilla Male Jedi Knight turned to the Dark Side of the Force during the early stages of the Great Jedi Purge due to his frustration with being discriminated by the Jedi for being such an angry being, by the public for being a jedi later on, by his people for being force-sensitive. And finally gave into the rage, becoming one of the early Inquisitors.
He would later die at the hands of a post-purge jedi after losing focus and succumbing to his hatred and wrath.
His legacy would be carried on by his son, Krehlikahin'glawkik.
