I was gonna guess Kabr the Legion less because he links himself with the Aegis shield. Though the teeth part doesn't add up. Therefore my guess is the LIGHT or better yet a Gaurdians SUPER. Why? Amahkaras Spine with ashes to ashes and the swarm grenade increase super. And the exotic arm has teeth in the description I believe. Also supers create orbs which are non-creation. As for the absence will provoke us, remember VoG hard originally (NEED WARLOCK WITH SELF RES) people get kicked for not having the right super.
