Oh thanks, otherwise I thought not to get there at all without online. It's even better, because the place is hard cheating to start the game.!!

Here's how to get a medallion on a pirate

Interestingly, on the Nexus there is no chance of a mod for such a medallion ??-)

I did not find any other options, I had to take a steam bath to find the ID of this medallion.

What does the medallion give?
