Cthire held a great knowledge of science, and was charged with creating and managing new forms of Warships, Warbeasts and Grakk. He rarely held a command post.
Cthire built the warship Torment. He captained it for a while, but Soulbane took it from him. Since Soulbane was more powerful and favoured than he was, Chire could do nothing about this. It is rumored that he was making a new, better ship before his death.
Cthire was generally a cool and logical individual, calculating each decision with lethal precision. However, he was prone to extreme fits of rage, during which he often killed large numbers of Grakk and sometimes Korgrath. Because of this, his minions usually left him alone in his chamber.
Soon after his death, it was discovered that he had created a special starship before his demise, a highly powerful vessel known as the Nemesis. The remaining Seven immediately set out to capture his ship.
