“Following the events of the Taken War, a newly created Fallen organization had begun looting and stealing resources, including items from the Black Armory, a secret weapon foundry that even the Vanguard did not know about. The sole survivor of the Black Armory, Ada-1, took the aid of the Guardians to help reclaim the lost stolen items that the Kell’s Scourge had taken. Throughout the season, Ada-1 sent Guardians to once hidden regions on the EDZ and Nessus in the hopes to locate Black Armory Forges. Another Fallen enemy had infiltrated the Last City and set up shop in a quarantined zone within the city, and Guardians were called to seek them out and destroy them. Once the  Scourge of the Past raid was dealt with, Guardians continued to focus on the remaining lost forges. 

Guardians also celebrated the annual Tower events, The Dawning and Crimson Days.”
