For what felt like centuries - monsters had a fragment of hope; that they would regain their freedom and return to the surface after being banished underground by humans. But when Frisk fell down, that dwindling hope was crushed with their every action.
But now, with Geno and his flawed plans, he is given a chance - a chance to change it all himself, and finally 'put this slaughter to rest'. What actions will Geno take to stop the endless cycle of mass destruction, and how far is he willing to go to break free of his shackles?
