I want to review this without giving away what was written. I am currently running a Planescape campaign in 5th Ed, and this is the perfect way to flavor some new druid NPCs for me. If anyone loses a character (again) or a new player joins, I would also totally allow this to be brought in on the players' side. It really fits into the feel of Planescape, for the way I run it at least. It is both familiar and alien at the same time as far as how druids are perceived by clueless berks from the Prime Material (Planescape fans get that reference). It is well thought out and decently balanced compared to other druid circles.
