(This chapter is told by Flowey, sorta like the genocide route. This chapter is not Cannon with the book. I have had most of the book planned out during the course of the summer.) "You really want to know what happened before you fell down?" Flowey asked Frisk. "Yes, I’m curious to know who this "Asriel" is," Frisk replied. "Alright I guess I can tell you," said Flowey.
A long time ago a human fell into the ruins.
Injured by its fall they cried out for help.
Asriel, the king’s son, heard the humans call.
He brought back the human to the castle.
Over time Asriel and the human became like siblings. The king and queen treated the child as their own, the underground was full of hope. Then one day, the human became very ill. The sick human had only one request, to see the flowers from their village. But there was nothing we could do.
The next day...
The human died.
Asriel wracked with grief and absorbed the human’s soul. He transformed into a being with incredible power. With the human soul, Asriel crossed the barrier. He carried the human’s body through the sunset, Back to the village of the humans. Asriel reached the center of the village, there, he had found a bed of golden flowers. He carried the human onto it. Suddenly screams rang out. The villagers saw Asriel holding the human’s body. They thought that he had killed the child. The humans attacked with everything they had, he was struck blow after blow.
But..
Asriel didn’t fight back. Clutching the human Asriel smiled and walked away. Wounded, Asriel stumbled home. He entered the castle and collapsed. His dust spread across the garden, the kingdom fell into despair. The king and queen had lost 2 children in one night. The humans had once again taken everything from us. The kingdom decided that it was time to end our suffering, every human who falls down here must die. With enough souls, we can shatter the barrier forever.
"It’s not long now Frisk, King Asgore will let us go, give us hope, and save us all," Flowey said. "You should be smiling, too. Aren’t you happy, excited? You’re going to be free!
