The Elder Scrolls IV: The Knights of the Nine

Basically a collection of dungeons with items at the end. The Ayleid actually being manifestations of the Daedra was a cool thing. It was also cool being able to see the Ayleid for the first time after they're hinted at the whole game. Kind of monstrous and terrifying. I can see why the slave races of men hate them so much lol.
Lore and story of the knights was pretty bland and generic. I guess if you're really into Elder Scrolls lore there's some nice tidbits but overall this is a pretty missable bit of DLC.
