Mt. Ebott. A mountain holding place a village like no other. Somewhere in this particular village, there lived a demon in its underworld. A tyrannical demon overlord in which manipulates, and controls beings' emotions, ways of behavior, and their temperaments. Some call him "The King of all Evil". Others call him "Demon King". Well, those are nice nicknames for this demon overlord. His name is Ralimos Regnum. Or as people believe in legends involving him, Ralimos. Anyway, he was sitting in his throne, watching his kingdom in its natural state. He was getting bored and sighed with boredom. He said:
"Every day just feels… boring."
He sighs once more, but notices a light coming from above. He digs and watches a clan of humans become friends with the clan of monsters from the underground. He gets curious and hears what they are saying.
"I believe we are going to get along just greatly." A human knight shook hands with a female lady goat named Toriel who smiled in return.
"I'm sure you boys would be interested in some Butterscotch-Cinnamon pie."
The humans cheered for the suggestion of the delicious pastry. Ralimos watched and with a sinister grin, he chuckled and as he walked to a side of his kingdom, he looked over a huge ocean of lava and laughed maniacally. He had a great plan in mind. A sinister plan. Ralimos had a great but sinister plan in mind.
"I'll disguise myself as one of the humans, frame Asgore for harming them, and then..."
He closed his eyes, and imagined a war between humans and monsters, and it ended with the humans winning victoriously with the monsters sealed underground.
"I'll release my terror upon earth!"
So it was settled. He assembled his demonic minions to help him with the human disguise. As they finished preparing their overlord with the disguise, the plan was now ready to be in full action.
