One of the most useful kinds of content for me as a DM is something that is more than a random encounter (like 2d6 goblins or whatever) but less than a full adventure, something I can quickly insert into a session over anything from 30 minutes to two hours. This is packed with that kind of material, and the encounters are at a very high standard with some that are just fantastic (it's worth it just for the Awakened Shrub encounter, tbh). Special mention also to the art, which is really stunning - nothics have never looked better.
