Here's some Prythian lesser fae world-building headcanons because I am so bored of human-looking hot guys with semi-pointy ears and literally nothing else.
Spring has several races of lesser fae that have wings like butterflies. They are the main farmers and bouquet makers for the Spring Court but they were targeted by Tamlin's father before his death.
Spring also has a lesser fae race that are a bit like fawns / satyrs but resemble sheep instead of goats or horses. They have fluffy white wool and ram horns for the males
Many lesser fae races migrate between the seasonal courts based on the season. There are the monarch fae, who migrate between Spring, Summer, and Autumn.
There are also the Kontio fae, who are bear-like lesser fae who travel between courts based on the season. They hibernate in Winter during the winter months, travel through Summer and Autumn on the Spring Equinox to settle in the Spring Court, then they travel to Summer and Autumn perspectively until it's time to hibernate again. They are one of the main lesser fae races in my Lucien backstory fic A Court of Embers and Sunlight :)
Sprites are common in all of the courts, but each court has their own unique variety based on the elements / main features of the Court. Spring has sprites that resemple petals and sleep in flowers; Autumn has sprites that glow like embers and hide in the colorful leaves; Summer has wood sprites and water sprites. Winter has snow sprites with frosty skin. Dawn has fae that only come out during the sunrise and camouflage with the clouds. Day has sun sprites that are completely gold and shine in the sun like jewels. And Night has star sprites that hide in the mountains and shoot across the sky like comets.
Winter has ice giants that hide out in the mountains. These became almost extinct after the Human War, and many believe they no longer exist.
Winter also has snow leopard fae with tails, spots on their white skin, and and fluffy ears that peek out from their soft white hair.
Summer has the Áfruvvá fae, which is a mermaid race that lives on the coast
Night has the Aranrot fae, which is a fae race with beautiful silver skin that glows and sparkles like a star. The race is all female, very stern and independent, and live proud sexual lives. Believed a virgin was an independent female who was answerable only unto herself. Associated with the galaxy.
Autumn and Winter have lesser fae that resemble wood lemmings. They are covered in soft fur, and have small paws with a flattened claw as their index finger. They have terrible eyesight but their sense of smell and hearing are 10 times better than the High Fae. They're called Sopuli Fae in my fanfic :)
These are a small precentage of my lesser fae headcanons and it's one of my favorite things to write. Like come on, it's so fun! Give me more, SJM 😩
