Kalecgos the Spell Weaver is the current Aspect of the blue dragonflight, after the death of Malygos. He often disguises himself as a half-elf, calling himself Kalec. Due to the blues being most in tune with magic of all the dragonflights, Kalec has the powers of a sorcerer and the strength of a warrior.
Prior to the Nexus War, Kalecgos was Malygos’ investigator, and became involved in the search for residual energies of the Sunwell. He opposed Malygos’ war against mortal spellcasters and became the blue dragonflight’s ambassador to the Wyrmrest Accord.
During the events of the War against the Lich King, Kalec decided to not stand with Malygos. He allied himself with Alexstrasza and the Wyrmrest Accord to help stop his former master.
At some point Kalec relocated to Azshara, fearing that the death of Malygos was a sign of weakness on the part of the blue dragonflight, and that Deathwing would send agents to assassinate the rest of the flight. This held true, as the black dragonflight invaded Azshara to hunt down Azuregos. Kalec can be found in Bilgewater Harbor, where he and Azuregos help low level Horde players to repel the invasion.
Meanwhile, the blue dragonflight struggled with the issue of appointing a new leader. Its members were torn between Kalecgos and Arygos, the two likeliest successors. Arygos believed that his kind should withdraw from the world and forge a new path while Kalecgos believed that they should play an active part in the world’s affairs. Ultimately, the flight agreed to meet at the Nexus during the astronomical event called the “Embrace”, where both of Azeroth’s moons come in perfect alignment, in the hopes that one of them would be selected as the new Aspect.
Arygos, who was secretly allied with Deathwing, attempted to have Kalecgos assassinated to ensure his own succession. However, his plan failed when Tarecgosa sacrificed herself to save Kalecgos, and he flees Coldarra, swearing that Neltharion will destroy them all. Kalecgos thus becomes the official successor to Malygos, as both the leader of the Blue Dragonflight and the Aspect of Magic.
Before taking up the throne of Aspect of the Blue Dragonflight:
Brothers, sisters. Arygos speaks of our troubled past. Indeed, we have suffered greatly. But I’d contend that we’re at least partly to blame for the scars we bear. Let’s turn from our old ways. Let’s not seek to extinguish magic from the world… …but to use responsibly for the benifit of Azeroth and all its inhabitants. It’s true that our choice here today will affect the destiny of our flight, and likely, the destiny of the world. May the Titans guide us. May we be inspired to choose with wisdom.
With the rise of Deathwing during the Cataclysm, Kalecgos the new Aspect of Magic aids his fellow Aspects and the mortal adventurers in the battle with the Black Aspect.
