As with the other Shattered Realm locations we've visited in the Season of the Lost in Destiny 2, the Ruins of Wrath hides some strange secrets. These Ascendant Mysteries are longer, more involved story beats hidden within the Ascendant Plane that demonstrate what's going on this season and why the Ascendant Realm is so important. In the Ruins of Wrath, the Hive-focused Shattered Realm area modeled after the moon, the Hive god of war, Xivu Arath, is up to something, and you need to uncover it and stop it.
There are two Ascendant Mysteries to uncover in the Ruins of Wrath, each tied to one of the beacons you need to align as you're working your way through the area. Here's where you can find both Ascendant Mysteries and what you need to do to solve them.
