Brian was one of the Blackheart Cousins, the other Blackheart Cousin being John Blackheart. Fifty years ago, Brian and his fellow cousin captured a great treasure and buried it on an island. They then scratched a map to their buried treasure on a gold medallion and divided it in two. As the governors were after them, the two split up to escape. He then decided to plunder Port Royal and was never heard of again.
