Balacgos was an elder offspring of the great aspect Malygos. As a caretaker of magic, Balacgos created a cerulean cube to deal with the unharnessed latent magic energy found throughout Azeroth, in an effort to keep it out of the hands of undisciplined practitioners of the arcane. The cube was designed to absorb such magic and hold it in reserve till a time the blue dragonflight had need of it. But Balacgos miscalculated and upon activating the cube the device absorbed his magic, leaving the dragon a lifeless husk. The cube came to be known as Balacgos's Bane.
