Once Upon a Time (He Would Never Be King)
He was the youngest of twelve. Twelve. He would never have been king if he didn't take matters into his own hands. It was so easy, really. Darling, darling Anna was so easy to manipulate and would've been just as easy to kill, except apparently her sister found out that love was more powerful than fear and he believed that that was total bull, but it had defeated him and that had to mean something.
He was strong, and far, far more evil than Maleficent because she couldn't kill, and he was so, so willing to kill if only he would get what he wanted. But apparently, that wasn't good enough. And now he would never rule. He'd lost on the Seven Isles, Arendelle, Auradon, and the Isle of the Lost. Even though Maleficent wasn't in charge. She was deluded and powerful, yes, but she didn't rule the Isle.
That honour befell Mal Lilith (although she went by Bertha to those who didn't know her true nature) le Fay, of the line Morgana, born to the arcane magicks, Truthseeker and Fae Queen, Champion of the Pale Rider. Alongside her served Evie Amara Grimhildejardöttir, Seducer of the Strongest and representative of Conquest, Jay Jafarson, a born-free genie and War's consort, and finally, Carlos de Vil, the Slaughterer and Chosen of Pestilence.
No one in Auradon knew, though, if they knew there were children with such powerful magicks on the Isle, they wouldn't hesitate to kill everyone in a blast (the heroes weren't as heroic as they liked to seem).
His son, Prince Hayden (because he'd never been disowned, not officially, although his mother had said she was disappointed that he was her final son. But officially, if he got out, he still had a home in the Southern Isles) was taught to be charming and ready and powerful and how to use his wealth to win friends and influence people.
Hayden could kill, and easily. Blood had no effect on him, and it was so so so so easy. His father taught him one other thing- revenge. He would get revenge on the bitch and her slut of a sister who had rejected him for an ice miner. They would pay and he would rule as he was meant to, his father would tell him. Revenge and power always came in the same breath.
Prince Hayden was let out by Queen Evie because they'd always had relations back in the day. And he let his father out, and his father married Anna (a beautiful wedding, with beautiful jewellery for the bride. Handcuffs and a collar went well with white) and moved to the Southern Isles, and that was that, but Prince (now King) Hayden married that infernally frozen bitch, who didn't age because she was frozen in time, from what they could tell, and he ruled Arendelle, which his father never managed to get round to.
(Because sometimes force was better than niceties.)
