Aesklos was Surisha's minion; he had symbiotic relation with her. He hunted for humans and drained their life-force. The success of his hunts was due to fact that he somehow was able to illusions to paralyze the victims in fear, and they were unable to fight back. He then returned to their underground lair and feed Surisha; that in turn kept him alive and gave him purpose. Tigra managed to convince Aesklos to feed on Surisha, and that killed them both.
