Fey type

Fey creatures have a damage reduction that is penetrated by Cold Iron weapons. Fey are usually humanoid in form, and are typified as having supernatural abilities and a connection to nature or to some other force or place. Often they are human size or smaller with a fondness for rapid small blade or range attacks. As in tales of old, the fey are feckless, clever, and quick to take offence. Fey often enjoy a riddle or song with some preferring to speak only in verse.

Unsurprisingly Fey are common in the Feywild, with Satyrs, Pixies, Blink Dogs, Red Caps, and Dryads being among it denizens. Satyrs and Dryads have also been found other locations like The Borderlands and Eveningstar.

The Fey are roughly aligned into Four Eminences or Courts, one for each Season, but they can shift on a whim.

Elder Fey amassing great power are called Archfey. The two known Archfey are Hyrsam, Prince of Satyra (Spring?) and The Prince of Frost, an Eladrin. Queen Titania of Summer has been alluded to, but not yet in the game. No Mention of Archfey of Autumn at this time.
