Trongar was a large minotaur king appearing in The Sword of Frost, the eighth part of Heroes Chronicles. He acted as Tarnum's bodyguard. When Tarnum took control of Nighon's armies to use them to stop Gelu from finding the Sword of Frost, he ended up with the beholders Neez, Kilkik and Zarm as his advisors and guards. After Zarm was killed in combat, Neez and Kilkik continued to serve him for a while, but they were cruel and sadistic, and lost their respect for him when they saw how reluctant he was to kill or torture his other soldiers. When Tarnum realized that his advisors were becoming more dangerous than useful, he hired the minotaur Trongar to aid him.
