Cheiron was a satyr and an immortal friend of Hercules, who had at one time journeyed alongside Hercules in his adventures. During one adventure, Hercules mistakenly struck Cheiron with his sword. Due to Hercules' immortal blood, Cheiron was left with a debilitating mortal wound across his stomach and was left in agony. No longer able to adventure, he retired to his home, with his mortal wife Amalthea and children Telemon, Peleus and Kora.
