Hope, the treacherous daughter of Dahak and Gabrielle, went to the Ixion Caverns and freed Callisto. Hope gave the warrior-goddess a mission: rid the world of Hercules. Callisto joined forces with Ares, and the two reopened the vortex to the alternate universe. When the Sovereign appeared, Ares snatched his pendant of Hind's blood -- the only substance that can kill a god. But Callisto ripped the pendant from Ares' neck and used the blood to kill Strife. Hope then sent Callisto back in time to kill Hercules' mother, so Iolaus convinced Ares to send him back as well.
