The underground was once populated with many monsters, all living happy lives. Until Chara came. They possessed Frisk, another human, and wiped out most of the monster race. Some of them are still alive, and they no longer trust humans. In this RP, this is taking place during or the aftermath of the Genocide route in Undertale. Survive as a monster or become a helpful human, trying to restore peace in the underground. Or, be the person who caused all of this (Chara).
