Luxord was a pirate ship. He was fearsome (if you knew what to look for) and dangerous and cannier than a city-bred thief.
Luxord was unique (how many ships flew black sails? Only one other), was luck incarnate, was offensive and warring and disinclined to avoid pillaging and wreaking havoc.
Luxord was the sound of cannons firing, was the smell of saltwater and sweat and gunpowder, was the feeling of losing everything you had, all at once, was the worst nightmare you never woke up from.
Luxord was a pirate ship, always sailing on foreign waters, towards some distant horizon.
