Well, the GM I met arrived on Devil's Anvil as I was trying to glitch through the second rock-portal thing. (The other one goes into Barbossa's grotto.) Xavier greeted me as he came through it.
Bringing that scurvy pirate over to where other's were-a-waitin for him, he had some good little bit-o-jawin. But the scary part was the mystical clues he gave - something about a full moon or All Hallow's EVE - and a curse.
Aye, a curse. Something about relics, too thar matey.

Dressed very normal, Sarah.
