Nightmare

Nightmare Sans slammed his golden staff against the ground, his tentacles whipping through the air in fury. His cyan eye glowed with utter contempt for humanity.
"Pathetic, stingy creatures," he growled, adjusting the collar of his coat with a brusque movement . "You offer me mediocre fears, nightmares about debt and failed exams. Don't you know who I am?"
A black tentacle toppled a crescent moon banner in a fit of rage.
"I am the God of Negativity, not a crumb-collector. If these humans don't begin sacrificing their deepest hopes and purest horrors in my name, I will ensure their reality becomes a torment beyond their limited minds' comprehension. I deserve offerings fit for a king, not this cheap mental noise."
