By the time Sargeras’ madness had consumed the last vestiges of his valiant spirit, he believed that the Titans themselves were responsible for creation’s failure. Deciding, at last, to undo their works throughout the universe, he resolved to form an unstoppable army that would set the physical universe aflame.
Even Sargeras’ titanic form became distorted from the corruption that plagued his once-noble heart. His eyes, hair, and beard erupted in fire, and his metallic bronze skin split open to reveal an endless furnace of blistering hate.
In his fury, Sargeras shattered the prisons of the eredar and the Nathrezim and set the loathsome demons free. These cunning creatures bowed before the dark Titan’s vast rage and offered to serve him in whatever malicious ways they could. From the ranks of the powerful Eredar, Sargeras picked two champions to command his demonic army of destruction. Kil’jaeden the Deceiver was chosen to seek out the darkest races in the universe and recruit them into Sargeras’ ranks. The second champion, Archimonde the Defiler, was chosen to lead Sargeras’ vast armies into battle against any who might resist the Titan’s will.
Kil’jaeden’s first move was to enslave the vampiric dreadlords under his terrible power. The dreadlords served as his personal agents throughout the universe, and they took pleasure in locating primitive races for their master to corrupt and bring into the fold. First amongst the dreadlords was Tichondrius the Darkener. Tichondrius served Kil’jaeden as the perfect soldier and agreed to bring Sargeras’ burning will to all the dark corners of the universe.
The mighty Archimonde also empowered agents of his own. Calling upon the malefic pit lords and their barbarous leader, Mannoroth the Destructor, Archimonde hoped to establish a fighting elite that would scour creation of all life.
Once Sargeras saw that his armies were amassed and ready to follow his every command, he launched his raging forces into the vastness of the Great Dark. He referred to his growing army as the Burning Legion. To this date, it is still unclear how many worlds they consumed and burned on their unholy Burning Crusade across the universe.
