He didn't want to get married. Especially not to the King of Purgatory, Richard 'Dick' Roman. Castiel enjoyed being free, he enjoyed the times he would escape the confines of the castle and explore the kingdom of Heaven before his father, King Charles 'Chuck' of Heaven sent soldiers after him to bring him home. One of Castiels favourite places to go was to the docks, the hustle and bustle of merchants making it a lively experience while the waves of the ocean calmed Castiel, allowing him to dream of a world far far away from the one he was being forced to live.
The Impala owned the ocean, in the captains personal view. She just looked so beautiful riding the waves. Terrifying to other sailors who got in her way, but beautiful to Dean Winchester. Being a pirate, one would think that his life was thrilling, filled with excitement, fighting, killing, purging, stealing, and adventure. But for the most part, Impala was calm against the waves, no exciting new adventures for Dean Winchester on the horizon. Only him, his ship and his crew, free to sail off into the sunset every evening. Until...
After ten years, the apocalypse seems to have ended, but no one can figure how, or why. Dean Winchester and his brother, Sam, had been hiding out in their bunker since the apocalypse started, separated from their father, with nobody but each other. The monsters they used to hunt were nothing compared to the hoards of undead that kept them confined to their bunker. Since it all stopped, they're free to roam the earth again.
On a supply run soon after the undead are gone, Dean runs into a stranger, Castiel. Traveling with him, his nephew, Jack. While Dean's general rule is to never trust anyone, he can't help but feel responsible for protecting these two, especially Cas. Intent on finding somewhere they can settle down and start to rebuild their lives, the four of them set off to find food, shelter, and a community to call home. What else is there to do after the end of the world?
