Long ago 8 human children would each climbed Mt. Ebott and fall into the underground where monsters have been sealed for years, 7 of these children would die unfortunate deaths but the final child Frisk was able to befriend all the monsters and free them from their underground prison but you already know that and you know the story of the first human Chara and how they tried to save monsterkind but failed, but what if all 8 humans fell in the underground together and what if their were two more humans to fall, let's see.
