New Dungeon: The Ruby Sanctum

The sacred Chamber of the Aspects beneath Wyrmrest Temple has seen kingdoms and armies rise and fall throughout history. For over ten millennia, the dragonflights' five sanctums have remained hallowed ground for dragonkind, undamaged by the chaos of the Demon Soul's creation and protected from the ravages of the Scourge thanks to a rare instance of cooperation between members of all five dragonflights. The red dragonflight, dedicated to the preservation of all life on Azeroth, has been at the heart of a tentative partnership between dragonflights, known as the Wyrmrest Accord, which the red dragons have guided from their sacred Ruby Sanctum. Draconic unity, at least in the face of grave danger, seems a real possibility.

And yet, suspicion has gnawed at all of the dragons of the Wyrmrest Accord from the moment of its creation. Immediately following the events that sparked the Nexus War, the leader of the red dragons, Alexstrasza the Life-Binder, instructed her children to scour the accord for any further evidence of danger from within. The red dragonflight swiftly uncovered the location of a clutch of twilight dragon eggs, the twisted creations of Deathwing the Destroyer, hidden away in the black dragonflight's Obsidian Sanctum.
