In the Shadow of Kings
The former Sorcerer-King of the city of Tyr. He was once said to be immortal and the most powerful of all the Athasian Defilers. However, after the construction of the Ziggurat a hundred years ago, he initiated a series of human sacrifices and took the life of hundreds of slaves over many months. Whatever Kalak tried to accomplish, he apparently failed, and he rapidly seemed to grow older and begun to lose interest in the ruling of the city. As Kalak payed more and more attention to the gladiator combats in the Arena, Tyr quickly deteriorated into what it is today.
He was killed in his own Arena by Shamash of Tyr; an action which initiated the bloody Liberation.
