All creatures which originated from The Feywild and The Shadowfell are considered Fey. The archetypal fey is characterized by a strange combination of lawfulness and chaotic-ness, mischief causing tricksters bound to strict codes. Fey are incredibly varied in values and temperament, but they tend to hold a stronger connection to the natural world than Humanoids.

Relations of other Races
Shadowfellian Fey and Feywild Fey exist in eternal conflict, fundamentally opposed in nature. Shadow Fey live in eternal dusk, creatures of monotone shadow and decay. Wild Fey live in eternal dawn, creatures of overwhelming vibrancy and vividness.
