Larian Studios Forums Divinity - Original Sin Divinity Original Sin - Help/Tips/Tricks Stones on first map?

I've cleared most of the first map, but I only have two stones, the first from the clinic and one from the murder room.

I thought Black Cove would have one since the pirates kept talking about it, but I didn't find one.

Are there others on the first map? Note I haven't done the church yet.

Thanks.
