If say in the future updates their was a tall tale and in that tall tale you get to make a choice. The choice is to side with flameheart or help protect with the pirate Lord who's side are you choosing. Also when you choose you can only unlock say a certain ship set and the other is permanently locked. Basically this would create a good vs evil in the sea of thieves world. And a new storyline unique to your choice.
I choose flameheart.
