Jack wanted to die by the rope, to join his buddies in the afterlife he had earned, dance one last jig for the devil, and go out as a rebel to be remembered, not a corpse that slowly faded. On the eve of his birth, so many years ago he could not remember it, he attempted the walk. Halfway there he fell to his knees. Two thirds of the way he couldn't even crawl any further, coughing up blood, but still trying to move closer, with the last of his strength. That's when he swore the last oath. "I'll follow any captain, in this world, or more likely the next, if they can help me get to that next world on my terms. If I can swing, as a Captain, I will take the helm under any force that helps me get there."
Some say that Torriaeu was in that crowd with death herself when the deal was struck, him using the pitiful wreck of a once mighty man as an argument, some say that he heard his voice on the wind, miles away. But what we do know is that 'Ol Jack got to the gallows, even climbing up it on his own two feet. And he never danced on no hang rope, no, no gallows would hold him. He shot the hangman with a hidden pistol, and the town was thrown into riot and rebellion. And when order was regained, the last reports had Captain Jack taking the Chronos out for his funeral pyre.
Now not many know about this, but I swear by Torriaeu's Trick it's true, but when he went to light the pyre it rained. And then the rain cleared, sunlight shone down on the Old Captain, and he decided that he had himself a debt to pay. So since that day, He's named himself First Mate Jack, and he's looking for Torriaeu, to sign his watchbill.
