Gredor was the magistrate of a village where Cassius the Centaur lived. He hated the Centaurs who lived on land owned by Perdidis. He conspired with Locus to kill Perdidis so he could take over the land and banish the Centaurs. Hercules foiled the plot and advised Gredor to resign and leave the village before the villagers retaliate. Gredor does what Hercules advised to him.
