Episode 3 , "Shameless Self Insert". CODEX: Fairies.
• Royal fae are a giant water bear, made of clouds. Although they can create Avatars to interact with "mortals", that look more humanoid.
Their insides are actually a pocket dimension. Roughly the size of a city.
They are a Cosmic Parasite, that latches onto larger dimensions, to feed on a "Cosmic Force". Which they absorb through mortals, they collected.
• Smaller Fairies, are really the fae's antibodies... and servants. Organisms that manifested inside them, from the moment they were conceived. Caring for their dimensional body, and keeping them healthy just by following their instincts... and living their lives.
• Fae antibodies were born with their Royal Fae. And couldn't die of old age. There were very few things that could kill them at all. They were immortal, and couldn't naturally reproduce. Looking after the royal fae's mortal descendants, for the sake of their Royal... and to fill their own void at being sterile.
• All Mortal Fae, have a rare "fae gene", that manifest every 7 Generations.
These mortal fae have light bending, telekinesis, conjuration, and longevity.
If exposed to enough Fairy magic, from their Fairy Godparents, mortal fae may ascend into Royal fae. Which is actually why Royals breed with mortals, to increase their own numbers.
It was rare, and skipped most generations, but mortal fae could be born from any family line exposed to a royal... even several trillion generations later.
• While fairy wishes were no "Monkey's Paw", Fae Antibodies don't actually have the power to affect reality.
Rather they guide the children's own abilities, as a living dimension, to create a complex illusion, filled with mirror images of the people they knew.
Fairies antibodies can use permanent conjuration, to create near any object, and are grand master Illusionist, but that's the limit of their powers.
If the child wanted something world altering, they would just make a fantasy, for him to play in... that would use "Tough Love" to teach him a lesson, according to Fae Morality.
These fantasies would teach all descendants, to understand the fae, and be worthy of their power. But in a safe... although painful, environment.
• As a Royal Fae was a living dimension. They are extremely magically powerful.
• While royal fae do collect mortals, they often pamper these individuals. Treating them like treasured pets. While their Fae Antibodies, help care for them.
