Deep within Manaforge Omega, Dimensius--the All-Devouring and destroyer of K'aresh--is slowly waking as his devoted ethereal followers use the Dark Heart to give him sustenance. If they succeed, they will unleash a being of unfathomable power that could destroy the very fabric of reality.
Overview
Dimensius attempts to Devour players almost immediately, and again every time he reaches 100 energy. His Growing Hunger increases with each cast, pushing the players' Collective Gravity to its limits.
When Dimensius' health is depleted, he pulls players into the Dark Heart where they must quickly fly with Xal'atath to safety. He releases his conquered rivals to halt players' advance and attempts to obliterate them with Extinction and Gamma Burst.
After a devastating counter-attack from the players and Xal'atath, Dimensius begins to Extinguish the Stars. Upon reaching 100 energy he again attempts to Devour everything around him, pulling his Accretion Disk ever closer.

Alleria and Locus-Walker returned to the Seat of the Devourer from the portal as it closes from behind.
Alleria Windrunner: We did it. Dimensius is gone.
Locus-Walker: Not gone...
Locus-Walker turn towards the Dark Heart as it stutters.
Locus-Walker: But contained within the Dark Heart.
Alleria Windrunner: As is Xal'atath.
Alleria chuckled.
Alleria Windrunner: A fitting end for her.
Alleria is wracked by ethereal screeching and a flash of Xal'atath staring at her laughing.
Alleria Windrunner: No! Wait!
Locus-Walker grabs the Dark Heart and it begins to cause an eruption as Locus-Walker screams in agony trying to resists. He begins to wither away and Alleria watches in horror before trying to reach him. Locus-Walker crumbled into dust and explodes knocking Alleria. She then wakes up as Xal'atath laughs and Alleria looks at her as she left the Dark Heart.
Alleria Windrunner: You...
Alleria Windrunner: What did you do?!
Xal'atath: I kept my promise.
Xal'atath: Together, we vanquished Dimensius. And I now have all I need to claim what is mine.
Xal'atath takes the Dark Heart and turns away and laughs.

Alleria grabs the remains of Locus-Walker as she stares at it in horror.
On the other side of the cutscene, Alleria has the portal opened.
Alleria has a gossip:
We battled back the darkness, but at what cost?
How should we proceed?
Alleria Windrunner says: We stopped Dimensius... but now his power is Xal'atath's.
Alleria Windrunner says: Locus-Walker should have listened to me. But what would it have mattered?
Alleria Windrunner says: Dimensius had to be stopped. But in the end, the one who profited most was Xal'atath.
Alleria Windrunner says: And now we must stop her--more powerful, and without my mentor, our ally who understood her best.
Alleria Windrunner says: I... need time. We will discuss this outcome later.
Growing Hunger no longer increases beyond 2 in Raid Finder difficulty.
Living Mass now leave behind 3 Excess Mass when defeated in Raid Finder difficulty (was 2).
Living Mass health reduced by 50% in Raid Finder difficulty.
Voidwarden health reduced by 30% in Raid Finder difficulty.
Duration of Soaring Reshii granted by Umbral Gate increased in all difficulties except Mythic.
Fixed an issue where Druids could not use Flight Form during the flying portion of the Dimensius encounter.
Developers' notes: The above changes are intended to relax coordination requirements in Raid Finder, as areas of Collective Gravity will be faster and easier to create and will more reliably protect players from Devour.
