It’s a very well-done adventure, with a good balance of combat and roleplay, mayhem and skill use in it. Okay the main idea may be a little old school (rescuing a unicorn filly) but it works very well here, and can help explain some of what happened in earlier adventures from the Kingmaker line this is meant to support. It helps to display the Fae enmity that your PCs will probably end up dealing with in the long run as well as serving as a break in an otherwise encounter-a-day and exploration adventure you may be using. Well done and I like how it’s handled; five stars.
