So this fanfic only takes the original trilogy as canon. My take on what happened to inspire the song The Hanging Tree.
Or at least, that's what they thought when they brought the elemental priestess to the vampire lord's altar, but the hero of the story once again comes in and starts attacking, fire and ice fly everywhere, and when the dust settles, the eight girls gathered are the only ones left standing, but the ritual can't be stopped, and the whole of the underworld starts breaking apart.
