Pathaleon the Calculator

Following the Sunwell's defilement, the vainglorious arcanist Pathaleon saw an opportunity to gain renown by aiding Kael'thas in finding a cure for his race's addiction to magic. This single-minded quest led him to join the blood elf prince on Outland and oversee his disastrous experiments. Most recently, Pathaleon has begun harnessing the Tempest Keep's otherworldly technologies in pursuit of fame and power.
