The black pearl- james pidgely- Defeating Claude d'Arcis

[Stormrunner]

IIRC, I didn't get him at the Thieve's Den fort.

Instead, I went through the Tortuga Graveyard (entrance past Fabiola) and down the hill to the right. When you enter the cave there, you come across a little military encampment. Claude d'Arcis was disguised as one of the EITC soldiers there.

Good luck!
