Like Demascus, Kalkan died many times only to be resurrected. Kalkan killed many of Demascus' incarnations.
Kalkan had a bestial face and large cat-like ears. His breath smelled like carrion.
Kalkan possessed Damos, an artifact of great power that allowed him to see into the future. The fact that Damos killed anyone who used it did not trouble Kalkan because he always rose again in a new incarnation.
