Calling Them Home
From Destinypedia, the Destiny wiki
Calling Them Home is an Adventure in the EDZ made available after completion of the adventure A New Frontier. It is unlocked at the same time as the adventure Poor Reception and the mission Combustion.
During the course of Calling Them Home the player strengthens the communication network established by Devrim Kay and Hawthorne before the player's arrival in the European Dead Zone, by placing signal amplification nodes across the EDZ. They do this to broadcast a signal about The Farm. The player further encounters the fallout of their assassination of Skexsis, Outcast Captain during A New Frontier, destroys Fallen jamming devices in the Outskirts, and ultimately travels to Sojourner's Camp to place another node for the network, defeat the Fallen there, and secure supplies for the Farm.
