(THIS IS VERY AU BASED. ASGORE / TORIEL ARE TOGETHER AND ASRIEL IS ALIVE. CW OF ABUSE / CHILD ABUSE, TRAUMA, AND DARK THEMES ARE PRESENT) It's almost been a decade since the war of the humans and the monsters had ended and five years after Chara's death. Centuries of conflict have left the Underground in a state of repair and despair. But, only hope remains for the Dreemurrs to fix the problem with the barrier without killing humans, as Asgore has promised to find a way to fix this with the help of his scientists. But, how can Asgore juggle both his duties as a king and to his family? Another problem arises when a human child mysteriously falls out of nowhere with strange abilities attached to him that make him very unpredictable. However, on the month that arrives, could it be coincidence that a human falls? Stay tuned for the Cry of Bravery!
