The war had been going on for over a hundred years. Toriel VS Asgore. Both children dead, one blames the other, both try to kill. Frisk; someone who was trapped in the confines of Toriel's castle. Finally gains access to the outside world with the help of two friends. They team up with our favorite characters too travel to the other side of the underground on a quest to find Rouxls and Jevil. Who had been presumably kidnapped by Asgore's forces. This is a story that's mixed with some medieval elements and doesn't have anything to do with circuses (except on thing but that's a spoiler). It also has both casts of Undertale and Deltarune with some (a lot of) new locations and main characters of my own.
