"My most revered master, your most loyal servant, Kel'Thuzad, greets you," Kel'Thuzad said reverently. At that moment, this Archmage of Azeroth, a Hero Rank powerhouse, prostrated himself devoutly on the ground. His head touched the earth, and his lips pressed against the dirt. Anyone who saw him like this would never have believed that the kneeling man was an Archmage.

Rather than saying Kel'Thuzad served the Lich King, it would be more accurate to
