The Trading Co. Office is actually a secret outpost for the EITC right in the middle of Tortuga. Rumor has that the EITC set it up to keep tabs on pirates, but apparently it's not very secret.
Location[]
The "Office" in the middle of town, across from Seamstress Anne's. The building is non-descript with no sign, like other Import / Export Traders will have out front.
Interior[]
The inside of the fake Trading Co. is pretty much empty since they don't actually trade anything. But, there are books on the shelves and assorted papers on the desktop.
Inside, you can find a Royal Navy Guard. He is guarding the desk and will defend it if you snoop around it. Pirates come here for The Black Pearl Crew Story Quest to find an arrest warrant for Carver.
Game Notes[]
The original POTCO interior of the Trading Co. Office was completely empty and Spartan, save for the table your pirate must search. It was changed in the 1.2.0 update to The Legend of Pirates Online.
