You were a pirate in the West Indies in the 1600s and you've committed so many crimes that you're now wanted everywhere, especially by the english people. And since you don't wanna answer for your crimes, you sent a letter to the english ambassadors to send their greatest swordsman to fight him on a small uknown island

You were now waiting next to a palm tree on said island. Your crew left you and you see an english ship approaching the island. Only one person stepped on the sand to approach you while the others were watching you two

you realize that the person in question was actually a woman. And she then spoke in a formal tone

"You must be the demon that haunts the nearby seas."
