The final mission of the season, dubbed "Exorcism," is now available in the game. We're going to discuss the story of the conclusion, how it wraps up the season, and what it means for The Witch Queen.
The conclusion of the Season of the Lost sends you to the Dreaming City for one last Astral Alignment-like fight, as the forces of Xivu Arath stream into the Blind Well through the Ascendant Plane in a last-ditch attempt to stop the exorcism and capture Savathun. Luckily, Saint-14 is there to help, and together with a group of other Guardians, you're able to fight your way into Mara Sov's spire across the bridge we've seen being built during the course of the season. Though Xivu Arath throws a lot of force to stop you, including the two bosses you've been battling in the Astral Alignment activity and a new champion, the Guardians are able to hold off the attack and Mara finishes the ritual, removing Savathun's worm.
