This free preview of Alea's Feudal Lords campaign setting does a good job of sparking interest in the overall setting. Based on this preview, next time I consider a new 4e campaign, I will definitely give Feudal Lords a look.
The wandering magister paragon path presented here integrates tightly with the Feudal Lords storyline, but by "reskinning" the fluff a little, you can easily use the paragon path in a different setting. I love the way that Alea has incorporated the brand-new sorcerer mechanics into the paragon path, with innovative uses for wild magic.
