William B. Pordobel, better known as One-Eyed Willy, was the pirate captain of the ship, Inferno.
Once a court jester for the governess of the Spanish Netherlands, he was banished for telling off-colour stories and playing practical jokes. Following this, he started his own pirate crew and stole millions worth in treasure from the king of England, Charles I. Charles finally began retaliating, sending out the entire Royal Navy to take down the infamous captain, which erupted into a mass war. Willy ordered his ship to flee, trying to escape being killed in the process; while in a cave, the Navy began firing, hitting the walls and creating a cave-in, which sealed the Inferno into a giant cavern.
Before Willy and his crew perished, he had a series of intricate booby traps set up in the caves that led away, in hopes to kill those who attempted to find him or those who attempted to escape. After that, Willy killed all of his own crew members, except for the loyal ones he trusted, because he didn’t want them to get to his treasure. While this was a strong defense, it was not foolproof, as one of his crew escaped to the surface with his map and the two pieces that went with it: a doubloon and a copper medallion. The legend of One-Eyed Willy spread around the locals, eventually becoming part of local folklore.
He and the pirates he trusted the most, all died in his cabin on the Inferno. It is likely that he himself expired while sitting down, as his earthly remains were found in the captain's chair.
Willy sat in his chair for nearly three centuries before he was discovered by Mikey and the rest of the Goonies.
You seek the last remains of One-Eyed Willy. Do not attempt this find if you are afraid of jungle environments, spirits, or mosquitoes. It may feel like a bushwhack but it actually is not. It's an old road leading to a city park. Good luck and happy hunting!
