The Lord of Naxxramas is an iconic character from World of Warcraft, with a rich history that spans numerous expansions and key moments in the MMO. Fans of WoW have memories of their encounters with Kel'Thuzad to this day, and now they hope to see him join the roster. Kel'Thuzad has been a long-requested character to appear in Heroes of the Storm, and was even picked as the most desired character in a fan-made survey that came out in May.
Kel'Thuzad is a powerful lich that worked under the Lich King Arthas to spread disease and destruction to all that oppose his master. Formerly a human mage, Kel'Thuzad now uses his powers to raise the dead with his powerful necromancy. While Heroes of the Storm does feature a necromancer with the Diablo character Xul, Kel'Thuzad's unique brand of dark magic would make him a very popular choice for the MOBA.
