    Summary

    The balance within the world was now broken, but as with such universal constants it always finds a way to right itself through natural means. A balance of magic and science is required. The humans prior tried to exterminate the existence of magic to no avail. Every death of a mage would bring forth another as the magic buried itself deep into a new soul creating latent abilities in a chosen human child. The Seven: justice, bravery, patience, kindness, perseverance, integrity, and DETERMINATION would live on. If one perished then the magic would attach itself to another chosen soul. The lone town that knew the truth of their past was their only sanctuary. A place for them to escape from those that wished them harm, but absolute power corrupts absolutely and thus this is how our story… begins.

    Frisk clambered up the mountain. The mountain of so many horror stories, myths, and legends. She refused to be frightened by such things, but her heart was still racing as she ascended the peak of Mt. Ebott. It was rumored to be the home of bloodthirsty monsters that were cast into the mountain as punishment for their loss against humanity. It became nothing more than a scary story. Her hands convulsed when she prepared to jump.

    Summary

    Riff wasn't your average 25 year old. She owned and operated her own classic auto shop, went to college, and did charity events for the local at risk youths and children's hospital. But outside of her professional life, one would never know. She went to karaoke bars, clubs, enjoyed Saturday morning cartoons in her pajamas, and was a photographer.

    She was also a monster hybrid.

    Life was pretty calm despite the chaos until one night she went out with friends to the new Mettaton club. That was where she met HIM... And life as she knew it got a whole lot more complicated.
