Let me preface this review by saying that I really don't like FATE at all.
I download these settings when they look interesting, and most fall flat for me as very niche ideas or what have you...
This one, however, is really good, like, REALLY GOOD.
I recommend players of any fantasy RPG system to pay something to download this setting module.
The artwork is quirky, and at times, downright lovely. Wait until you see the Emerald Knight in its full glory, or the alien line up piece.
OK, what is this about? A low tech setting, potentially fantastical, but mediaeval-like in technology and feudal set up, is invaded by space (or dimensional) aliens. Which aliens? A quick idea generator is included, as well as defined powers for comparison to other systems, for outlining them in a manner germane to your chosen game system.
Imagine the Emerald Knight as a Green Slaad and the invaders as Githyanki, for instance.
Again, well worth a paid download.
