Dredgen Lightbearer

Dredgen Lightbearer is an NPC in the forge of Oblation: Immolation, the third and final exotic mission in the Cull's Shadow chain. After Ir Gohl is defeated, Guardians interact with the Lightbearer in the middle of the forge, which spawns a reward chest containing the Soulfire Skewer catalyst. Immolation is unlocked by completing Oblation: Soulfed.
