History of Plaguelands

The Plaguelands is an Earth destination region in Old Russia, near the Cosmodrome, added in Rise of Iron. The Devil Splicers (House of Devils) spread SIVA there. In Destiny 2 it is reached via the Iron Tomb mission, with the Lords' Watch landing zone, and houses Cabal, Vex and Fallen forces. In Ash & Iron, Cabal's Watch is set in the now SIVA-free Plaguelands.
