For the ask for Klaus and Caroline as king and queen :) (I'm sorry I don't know where I went with this at all)
He ruled with an iron fist. He was rash, quick to anger, thwarting any threat to him and his own without a second thought. He was the stuff of legends; parents still told their children cautionary bedtime stories about him. He was darkness made real. When people talked about him, they said he cloaked himself in shadow- As if anyone could really cloak them self in shadow- that his eyes glowed red- My eyes haven't glowed red in five hundred years- and if you saw him, he was sure to be the last thing you ever saw- That one at least isn't that much of an overstatement. He ruled by fear, and oh they feared him. Everyone. The other vampires, the few- one, she reminded him- other hybrids, even the humans, those who believed and those who didn't. He didn't just rule by fear though, no to many he became fear personified. There was one though who didn't fear him, who stayed by his side through everything. And somehow, she loved him, as much as he loved her, he was sure.
She, for all her years, managed to keep a shred of her humanity. She ruled in justice, though she could kill without blinking if she needed to. And she had, and she would again to protect the people she loved. Especially her own dark king. She was light though. Everyone who met her swore that she gave off her own light. She became a goddess of myth. Some compared her to Persephone, taken from her world by the dark Hades. If she was ever near when such words were uttered, she was quick to rectify the teller's beliefs. Amidst everything, she had chosen to be with him. For better for worse- He tried to keep things strictly in the better category- for richer for poorer- The poorer part would probably never be a problem for them of all people- in sickness and in health- Well, she didn't actually get sick- as long as they both should live- She planned to be with him until the world ended around them. Sometimes, when she thought back on her life, she would still feel a shock that she was with him, that she had married him some three hundred years earlier. But she didn't regret it.
She was quick to compassion with the people he saw as wronging them; she saw the best in them. After all, she had been semi-wrong about him, and she wanted to give other people the same opportunity to prove her wrong. People took advantage though, of her kindness, of the seeming air of naivety that clung to her even still- a perk and curse of being eternally seventeen- and he had had to save her more than once, each time lecturing her on the virtues of not trusting anyone. She knew he was scared though, for all his strength and prowess, she had become a weakness, something he was afraid of losing. And when she did things that worried him, that almost caused her death, he reacted more violently toward his victim than he normally would. Still though, she would approach him afterwards, kissing him softly, sweetly, giving him her love and proving that she was alive and safe.
And she tried to curb his temper when she felt it was unwarranted. The merciful right hand some called her, the queen others, the queen of the damned as both a slur and a joke in others, one man still referred to her as Blondie, amidst her husband's scowls and muttered threats. He called her love, and angel, and his, his queen, and Mrs. Mikaelson on occasion. But Caroline, oh she loved the sound of her name rolling off of his tongue.
Sometimes he tried to make her fight, make her more like him. He loved her light, but he worried for her. He was indestructible, but she was not. And he was cruel sometimes, he would admit, in the name of her safety. They all called him the King, just the King, and he would not tolerate as she did nicknames or slurs. He tried to stop them from calling her anything but his Queen, his wife, but she stopped him, saying she didn't care what they called her. Still, to some people he was Klaus, Niklaus, but to her he was Nik, and he loved the way the three letter world would roll off of her tongue, differently depending on if she was happy, or mad, sad, or if she was writhing beneath him in bliss.
They ruled together, moving from city to city on a whim. He the king of darkness, the king of shadow and mystery and cruelty. She the queen of light, of mercy and love and compassion. And yet, they affected each other. Yin and yang. Because he was capable of mercy and love, just as much as she was capable of cruelty. In then end, they were two sides of the same coin, and their subjects knew that they would do anything for the other.
