If I had to choose a single word to describe "Bay of Spirits" it would be evocative. The setting drips with just enough detail to leave you wanting more. As a DM it leaves enough room for you to make it your own, and to easily adapt it - wither to BX, 5E or whatever other system you like. The artwork and maps are perhaps the most wonder ful part. I'd urge anyone looking for a stand-alone setting, or perhaps a micro-setting for insertion into a larger game world to take a look.
For $2.99 - this is plenty of material and has relatively few errors when it comes to typos or grammar. Nothing worth calling out.
