Y/N and her family are from Starlight Springs, a small village on the largest island of Starlight Isles. She's never had much, and she's never needed much, only wishing to be one of the only writers in Starlight Springs. She's never wanted anything to do with the royals who oversee Starlight Isles' business, she never asked to get tangled up in the royal family's lives. She never thought she'd ever get the chance to even know one of the royals. Until her family gets an invitation to a royal ball, hosted by the king and queen, celebrating their victory in a war with a kingdom overseas that's been going on for years. Y/N's life gets turned around, flipped upside down, but perhaps that's not a bad thing. Perhaps being entangled with the king and queen's eldest son, Nightmare will make her quiet, average life a little bit better. ...Or, perhaps it will cause everything to go downhill. This is the unstable, snappy, corrupted Prince of Starlight Isles, after all. ~~~~~~~~ Hi, y'all! Sighnerd, everyone's favorite (not really™) Author here! You wanted this, so here it is :D I love royal!NM tropes that AREN'T just him being the King of Negativity. Him being part of an actual royal family is amazing (either him as king or as prince). My other NM x Reader did pretty well, so I'm hoping this does as well. No actual upload schedule, just whenever I feel like. Cover art is by me !! Characters do NOT belong to me, they belong to their respectful Creators (Y/N obviously belongs to you). Soap belongs to my bestie Soap, and Demon belongs to my partner, Demon <3 The only characters I own in this are Y/N's family, I made them up purely for this and they will probably never be used again :] This is gonna be a slooooooow burn! Also touches on some dark things like abuse, so go into this with caution! Hope you enjoy !!!!

Heya! This book will be a bit of a slow burn, which means that all the ~romance stuff~ won't happen until a little later in the story. ~~~ Twenty year old (Y/N) has sworn her undying loyalty to none other than Nightmare, one of the most feared villains in the multiverse. She's been working with him for years, since she was seventeen, but she's never encountered the infamous Star Sanses. She wishes that she could meet them, she hopes that she'll be able to fight them some day and end their existence. Her ultimate goal is to impress her boss and to prove herself to everyone who told her that she wasn't good enough. Will her wish change when she encounters the Star Sanses? Completed 12/24/2021 ~~~ Pronouns used in this story are she/her Disclaimer: None of the art used belongs to me!
