William "Old Bill" Seacaster is a great adventurer with a great deal of fame who clearly made his wealth and his name in "heroic", while others call "nefarious", dealings. He is the father of Fabian Seacaster. He is the most pirate-y pirate to ever pirate. He wears a tricorn hat, an eye patch, and a long coat, with a saber at his side. Bill Seacaster is a very loud, intense, and volatile person. He takes pride in who he is and is not ashamed of the way he amassed his wealth. He is a pirate, and takes offense when people suggest otherwise, because of what he's done to get the title. He is extremely fond of his son and re-lives his adventuring days vicariously through him. He compliments him often, though this high praise tends to set very high expectations for him as well, which puts a strain on their otherwise very loving relationship. He's rich enough that he can hire cars to drive around for him.
