Another solid entry in the Paradigm Explored series, Fairy-Faith explores the worldview of mages who derive their workings from stories of the Fae. It includes notes for crossover with Changeling, some solid merits/flaws, rotes, and wonders, but by far the most interesting thing is the discussion of House Diedne. That discussion is full of great plot hooks, and is the portion that I am most likely to use in a game. Overall, a great addition, and a strong recommendation for anyone looking for more paradigm deep dives.
