Vox Obscura
From Destinypedia, the Destiny wiki
Vox Obscura is an Exotic Quest added with Season of the Risen that can be accessed from Savathun's Throne World. The quest becomes available after completing the first 4 steps of the Operation Elbrus Quest. After talking with Saladin in the HELM, Empress Caiatl will come up on the war table and debrief you about the mission. She will then give you the exotic quest named Kill the Messenger. When the quest has been completed, you will be rewarded with the Dead Messenger Exotic Grenade Launcher. When the master variant of this mission is cleared, you will be rewarded with the Dead Messenger Catalyst.
