"Next to nothing is known about who might be responsible for the assault on the Ruby Sanctum: the black dragonflight is not known for forgiveness or patience, but its numbers in Northrend are surely limited. What force would be powerful or daring enough to assail the stronghold of these ancient wyrms? How could such an enemy sneak by the temple's guardians undetected? Surely an approaching air or ground force would have been caught by Wyrmrest Temple's defenders.
For the moment, the members of the accord and their allies must assume the worst scenario that they can conceive of: that all life within the Ruby Sanctum rests on the precipice of extinction, and only immediate intervention will prevent the red dragonflight from being decimated. They'll find that the truth is far worse."
