The Wyrmrest Accord was an alliance of the remaining four dragonflights — the red, bronze, green, and even black flights — against the blue dragonflight's crusade against magic users. The red dragonflight was the most active of the four, with a large number of red dragons guarding Wyrmrest Temple itself.
The Nexus War
The Wyrmrest Accord was founded by Alexstrasza following Malygos's declaration of war upon all mortal spellcasters. She gathered together representatives from the other three dragonflights, both to oppose the blue dragonflight and to defend the Dragonblight against the undead Scourge. At the top of Wyrmrest Temple was placed a massive sphere, the Orb of Unity, as a symbol of the dragonflights' alliance. Eventually the blue dragon Kalecgos journeyed to Wyrmrest Temple as an unofficial ambassador to the blue dragonflight, openly declaring his opposition to the Nexus War.
The Accord is Broken
This section concerns content exclusive to the Warcraft novels or short stories.
With the defeat of both Malygos and the Lich King, the Wyrmrest Accord's activities lessened. Alexstrasza began reaching out to the remaining members of the blue dragonflight in a show of good faith, and the representatives of the black dragonflight mysteriously disappeared. After the Shattering, the Wyrmrest Accord began meeting with certain blue dragons, including Malygos's son, Arygos, to urge them to select a new Aspect in order to help restore the shattered world. However, Arygos was still angry about the death of his father, wondering aloud if Alexstrasza would simply kill him, too, if it became convenient.
During one such meeting, Wyrmrest Temple came under attack by the twilight dragonflight. The twilight dragons lured the defenders away from the temple, allowing their agents to slip into the sanctums within the Chamber of the Aspects and corrupt all of the eggs within. Their deception was discovered by Alexstrasza's consort, Korialstrasz, who sacrificed himself to destroy the sanctums and all the eggs contained within, heavily damaging Wyrmrest Temple in the process. Consumed with grief over the loss of the eggs, and faced with the possibility that her love might have betrayed them to the twilight dragonflight, Alexstrasza shattered the Orb of Unity, effectively ending the Wyrmrest Accord.
