In the 5e Monster Manual, we find many of D&D’s traditional fey – pixies, satyrs, and sprites, among others. This… falls a little short of both the variety and threat level I would like to see for the fey. I mean, the Archfey are potent on a level with the Nine and the Great Old Ones, judging by their significance as warlock patrons. This article, which might become a series, introduces a variety of higher-ranking fey creatures. There is also a knightly order (intended to be one among several) for those who serve the Archfey. This is going to become real obvious, real fast, but: I love me some Changeling (Dreaming, Lost – both awesome.)
Fey knights wander the Feywild, the Material Plane, and other places as they undertake quests for their lords, the Archfey. When not traveling, they defend their lord’s palace, or the halls of their lord’s vassals.
Pride drives fey knights to seek glory in battle; they rarely refuse any challenge that they have any hope of succeeding. They are the flower of fey chivalry, punctilious in manners and exquisitely refined in bearing.
Fey knights are quite similar to high elves in appearance, but with an otherworldly sheen to their skin and a palpable aura of majesty that few high elves can match.
