The Sidhe Duine are strange creatures often mistaken for Fae but they are capable of true death. It is believed they are a byproduct from the binding and breaking of the Fae Queen Viilnor. The Sidhe cannot be seen by the Gods as they are black holes of faith and belief, this also means magic that flows from Septriss doesn’t work on them. The bite of Iron kills their magic, and the bite of silver ruins their bodies, the bite of both is the only way to kill a Sidhe. Stakes of Rowan and Hawthorne can place them in endless sleep until they are removed.  All Sidhe are capable of using Glamour and normally wear beautiful visages though always uncanny or abstract. The Sidhe are creatures of the Mind and feed of aspects of it.

The Duine le Masc the most deceitful of the Sidhe appearing as beautiful inhuman creatures with too big eyes. They resemble whatever sex appeals to an individual and is an exaggerated form of erotic beauty. They often dwell in darkness as their forms in light can be uncanny. When not wearing their glamours the Duine le Masc take on androgenous forms with no body fat long eyes that bend extend to the sides of their heads slightly, large thin teeth, and large clawed hands. Duine le Masc feed off creativity, inspiration, and vision and they prey upon artists keeping them as pets in their near eternal halls. They are powerful creators of glamour making dreams appear reality. Their glamours can mimic the sensation of wind, flesh, and warmth.  

The Duine Ciuin are a form of Sidhe who wear night as a cloak with great batlike wings spangled in moving visages of night sky. They make no noise unless they wish it they are dealers in contracts and have taken on roles as brokers for Kalm.  The Duine Ciuin generally take the form of nocturnal animals and shun the light. They must follow the laws of hospitality. They have four arms each hand having three fingers, a thumb, and spur of bone, bodies with no fat and too big eyes facing fully forward. Their skulls are longer ending in a point. They feed off the voice leaving those they claim without a voice, lost for words, or with dwindling vocabularies. The Duine Ciuin like to wear sky and elements make their clothing from pieces of reality. They wield less glamour than the Duine le Masc but can capture pieces of nature and bind them for their own uses. They are powerful wielders of sound able to silence and bolster sound to weaponize it. 

The Duine Aisling are a form of Sidhe who plague the sleeping and dreaming. These terrors of the night appear to have no body fat their eyes and mouths seem to stretch beyond the confines of their heads. Their smiles always hold too many teeth opening to exposed ever more rows. They have six stubby legs that support their lower halves; they haves arms that can stretch out for over a dozen feet. They feed off wakefulness and calm preying on the sleeping stealing away their rest and peace of mind. Those who wake while they feed feel paralyzed with their terrifying visage above them. 

The Duine Craicinn are the most monstrous of the Sidhe appearing often as nothing more than glowing collections of eyes beneath mounds of skins. They are terrible predators who feed off identity and self, draining people of memories, personality, and drives. They leave people and beasts empty husks and then not even that as they tear off their skins and add them to their collection. The Duine Craicinn can pull on these skins to take the form of beast or man their forms often amalgamations of all their collected skins. Some collect the skins of the most beautiful of a given species so they can be beautiful. They are the weakest at Glamours but their ability to take the form and traits of beasts make them dangerous foes.
