Duality (dungeon)

Duality is a Dungeon that was added to Destiny 2 in the Season of the Haunted. In it, Eris Morn sends a fireteam into the mindscape of Calus, only to find it a schism overrun with his Nightmares. Guardians must fight through the shame haunting the emperor to steal knowledge from the deepest parts of his consciousness.
