FlowerFell

A long time ago, a human fell into the underground. This was the seventh and final human needed to break the barrier. The monsters had faith that the human would set them free. The human, however, killed their king, sending the kingdom into despair. The monsters turned to violence and cruelty to fill the void of hurt left by the human. When the same human happened to fall down the mountain again, the timeline is corrupted by a certain flower trying to take over the power to RESET. This allows for a flower blossom to grow on the creature with enough power to RESET. This, of course, doesn't affect the flower that can RESET, but once the human regains this power, the flowers begin to grow. With the hostile environment already in place, how can a weak human survive without RESETing multiple times? And what happens when the flowers begin to consume their body? The human will need someone to protect them, but who would take care of a human that destroyed everything they loved?
