Terul was the servant of the mage Zorun Tzin. He appears in the third of Richard A. Knaak's Sin War novels, The Veiled Prophet.
Terul was described as being a huge, lumbering 'giant'. His head was described as being 'too small' for his body, and his face resembled that of a primate. Needless to say, Terul was not overly intelligent - he was barely able to speak at all, usually only grunting separate words.
After making contact with the remains of the priest Durram in the jungles near Kehjan, Terul was possessed by the vile specter of Malic, effectively killing him. His body was destroyed by Uldyssian several days later, who almost incinerated the giant with his awesome powers.
