From Destinypedia, the Destiny wiki
Dredge Chieftains are Major Scorn Chieftains that appear as part of the Ether Ritual Public Event. They can be found in both the Dreaming City  and Savathûn's Throne World, as well as the Tangled Shore, when it was available as a Destination.
Dredge Chieftains are encounter during the Ether Ritual Public Event when it is active. They will each spawn one at a time – one of each element – among other, weaker Scorn enemies. To progress the event, participants must eliminate three of these Chieftains before facing off against an Ether Abomination, serving as the boss. After a Chieftain is killed, the destroyed Servitor that they spawned next to will emit clouds of Concentrated Dark Ether, which will hover towards the larger Servitor in the middle of the ritual site. If you are successful in destroying all of these clouds as they appear, you will trigger the Heroic version of the event.
