That's No Island. It's An Adventure!
The Guild of Thieves
It’s what the thieves’ of this Island call their guild. You don’t know much is know about them yet, but it’s well-known that they employ a small group of children as pick pockets & scouts. The island guard suspects that they operate out of some cave salong the coastline, but have had no luck finding a way in. the PCs suspect that Barakas might be a member, or at least has connections in the guild. Alderos has a hunch that they’re involved in the explosion at the docks.
