Oliver Tressilian was a distinguished gentleman hailing from Cornwall, renowned for his pivotal role in aiding the English forces during the monumental conflict against the Spanish Armada. His gallant deeds, however, were overshadowed by treachery, as he fell victim to the ruthless machinations of his half-brother, who betrayed him in a bid for power and wealth. 

Fleeing the dangers of his homeland and seeking solace from his brother's malevolence, Oliver journeyed to the exotic lands of the Middle East. There, amidst the vibrant markets and the tales of adventure that echoed through the bustling streets, he embraced a daring new identity as a Barbary pirate. As he navigated the perilous waters of the Mediterranean, Oliver not only sought to escape his past but also to forge a new destiny, filled with high-seas adventures and the thrill of the chase.
