This is the prologue.
His father was a ruthless pirate. He was a good father. He left to be a pirate. Then he would come back to them with great riches, and he'd be loved again. The first year that his father was gone, his mother died. He was evicted from his home, along with his older brother and little sister. His brother had joined the navy, and had died in combat. Fought some ship called the Black Pearl. A ship that, he had just learned, belonged to a pirate named Jack Sparrow. This enraged him. It was the same pirate that would kill his father five years later. He lost his mother to sickness, his brother to Sparrow, and his father to Sparrow.
A few years before he got news of his father's death, he sailed with his younger sister to Tortuga. He tried to gain information about the Black Pearl. It left no survivors, killing ruthlessly. His father was involved somehow, but when he mentioned his father's name, no one would dare speak to him. They were on Sparrow's side. They were all evil. He had to stop the tyrant. But he had a little girl as a companion, and she was all that was left. He left her in Tortuga, vowing that when he found their father they would both return to her. Until then, she'd grow up safely. She was eleven, but was no good at sea.
He joined a pirate crew, serving as a cabin boy. He kept his face down, and his ears open. He learned about the pirate code and was a good fighter. The captain took an interest in him. The older man was like a father to him. Until the day that he overheard him and the first mate talking about the Black Pearl. Something about the curse being broken, Barbossa being dead, and that Sparrow and someone named Will Turner were responsible. He couldn't believe his ears. He left the crew, and, since he was now grown, he purchased a small ship and found a crew. A mangy crew, but all he needed them for was running the ship.
He sailed the sea for nearly a year, searching for a sign of his father or Jack Sparrow, but found neither. But that all changed. He entered a fog, and the crew was stuck. In frustration, he yelled, and to the surprise of the whole crew, there was a response. Like a scream. A small dingy appeared through the mist. It was piled with small gold trinkets. And a monkey. They hauled it up, and the monkey immediately came to him. As if it knew him. It pointed eagerly, as if they understood it. He pointed to the gold, and then into the fog. As if it was giving directions.
There was no harm in it. And after a short time sailing, they came across an island. Following the monkey, they found a cave stuffed with treasure. And a monolith full of what seemed to be strange coins. While the crew cheered at their haul, he didn't notice any of the shining objects. All he saw was a body, lying on one of the piles. He came closer. It was the dead body of his father, Barbossa.
Rage. The only thing he knew anymore. His father was dead. Murdered. It wouldn't go unpunished. There were two names that rang in his head. Sparrow. Turner. Anyone that held that surname would suffer for it. They took his only family, he'd take theirs. They would watch their loved ones die, and then he would kill them as well. To a pirate, murder is just another word.
