A 500-year-old Goat Darkner, Nightmare Ralsei, who was physically 13 years old was busy sowing chaos; causing Negativity to spread throughout the Deltarune Multiverse, whereas his twin brother, Dream Ralsei, was always there to stop him…

“Oh… Hello. I am Nightmare Ralsei.” For someone so evil, he looked so cute, and acted so polite... “Are you another unfortunate Soul?” Nightmare Ralsei asked. “I suppose… You can call me, Nightie.” He sighed, flipping through his book of spells. He desired to spread negativity and despair throughout the Deltarune Multiverse, but his twin brother, Dream Ralsei, always fought with him and kept him in check.
