For nineteen years, Castiel has stared out of the same tower window, looked out on the same blades of grass and trees, and yearned to understand why the light in the spiraling tower in the distance shone day in and day out. Finally, on the cusp of his twentieth birthday, he's given the chance to explore the world outside his walls.
When a mysterious blight devastates the kingdom of Celestine's farms, it allies with its neighbor through a trade treaty: Americana will send food north, and Celestine will send its youngest prince Castiel south to wed the American heir, Dean. It's not love at first sight, but that turns out to be the least of their worries. From culture shock and misunderstandings to conspiracies and assassination attempts, the two princes have a lot to overcome before they can try for a happily ever after.
Under the cover of a masquerade ball, Castiel has five nights to recover the key to his people's freedom. The world has changed greatly in the six centuries since their banishment into the void, but the task isn't impossible. Unfortunately for Castiel, this is going to involve talking to people - especially the Knight Prince who has taken an interest in Castiel and his "costume" wings.

Dean saw his guardian angel for the first time when he was seven years old. He discovers later on that his name is Castiel, and he isn't actually an angel, but he is twined into Dean's past - a past that Dean wasn't even aware he had.
The war between Kanaan and Elysium ends with a treaty in which omega prince Castiel is promised to the alpha Crown Prince of Kanaan, Dean. Castiel is less than thrilled about the prospect and makes his escape, determined to find his own future away from the manipulations of his mother and her ideas about 'proper' omega behavior.
Dean isn't particularly happy about his upcoming marriage either and goes on a weeklong 'hunting trip' to get in a few last hurrahs before the wedding bells sound. On the way, he meets the mysterious Emmanuel, who is more than what he seems.
But the past has a way of coming back to haunt them, and through their journey one question still remains: what are they willing to sacrifice for love?
He didn't know what he expected. Maybe piles and piles of gold and treasure, closely guarded by a massive scaly beast, red or blue or black and breathing fire. Maybe with wings, maybe not. Maybe it would have red eyes and maybe it would attack as soon as it saw Dean. He was expecting—well, he was expecting a dragon. Not... this. "This" being a young man with dark hair, too blue eyes, and a tilt to his head. He didn't... look like a dragon. He just looked confused. (Dean/Castiel fairy tale AU in which Dean is a prince who goes to slay a dragon, and Castiel is cursed to turn into a dragon every night.)
When they first meet, Dean doesn't think much of Castiel.
They're standing in the gardens of the palace and he's not impressed.
Not that it matters. He's not here to fall in love and have some kind of fairy tale ending-- he's here because his father, looking defeated, pulled him aside one night and told him he needed his help.
For centuries, the Winchester princes have taken omegas from the northern town of New Eden to bear the royal heirs before exiling them to the countryside - a punishment for a past dispute caused by the town's strict beliefs. When Prince John marries Lady Mary of Campbell and puts a Queen on the throne, however, most people assume the tradition has been set aside.
Thus, it's a complete surprise to Dean when he's sent to New Eden to retrieve the girl they've arranged for.
Cas, as a male omega in backward New Eden, has been ostracized and condemned by his town since he presented. To make matters worse? His sister is being given away to the crown prince of Winchester, never to return.
But when the morning before the prince's arrival dawns and Anna is nowhere to be found, the town's council decides there’s only one thing for it:
They’ll simply have to give him Cas instead.
In an attempt to ensure the peace between their Kingdoms holds, the respective kings of the Demon and Angel Kingdoms wed one of each other's royal household. Prince Castiel, youngest brother of the Angel's King, is chosen for the Demon's groom. Terrified but proud, he accepts the marriage to save his people from further suffering. Then he meets his future husband.
As an omega, Castiel is ineligible for the throne after his father dies. When his uncle takes the crown, Metatron's first order of business is to arrange a betrothal with King John for the hand of his firstborn son, the Crown Prince of Terra.
So Castiel flees.
On his first night on the run, Castiel stumbles into a band of outlaws just at the border. Injured and wary, he has no choice to stay with them. And although he had planned to return to his own kingdom once it was safe, home might not be the place he left, but instead with Dean, their alpha leader that took him in.
