All the Blue Dragons, aside from Malygos the Spell-Weaver and a hand-full of dragon whelps, were killed in the War of the Ancients, but when Alextrasza was freed from the Orcs after the Second War, she gave the maddened Malygos some of her eggs to revive his flight. Some eggs were also preserved from the times of the War of the Ancients by Nozdormu at the request of Krasus when he was sent back in time, kept safe until after Malygos regained his sanity.

Norgannon, the Titan lore keeper and master-magician, granted the blue dragon, Malygos, a portion of his vast power. From then on, Malygos would be known as the Spell-Weaver, the guardian of magic and hidden arcanum.
