121st Hellcrawler Troop

After several successful missions the 121st Hellcrawler unit was being observed for Arbiter Status. They were sent on a covert mission on Perippe to deal with a potential psionic incursion. Whatever happened within the targeted facility remains classified, but the 121st Hellcrawler Troop was designated Terminated shortly after, and their files were archived.  Two items of interest were retrieved from the operation and attributed to the efforts of the Troop; a vial containing an unknown liquid substance and several fungal like minerals mined at the site.
