The fae are a curious category of living beings. They are born when a collective of land manifests a mind of its own. They are rather complex to understand.
During the first age, when emotions and thoughts were spreading across the world, plants, lakes, mountains and sometimes even the wind and the fields were starting to get permeated by this new sea of unseen. After a while, close to the end of the first era, the many collective lands started to develop minds of their own, and not much later, they were able to manifest a physical vessel, and from this physical vessel a myriad of physical vessels, each with its own personality and behaviour, thought they are in fact the same being, they still act, live and exist as if they were independent individuals, but do not mistake their behaviour with ignorance, every fairy knows where they come from and know that they are deep within the same entity and share the same soul.
Each Fae cluster, as some humans like to say, manifest a form in a different way, some might manifest perfect human like form while some others, might manifest a complete beast form, some might manifest half human half beast forms, some favouring a more human shape and some others favouring more a beast shape, some might mix plant appearance and beasts, some might mix plants and humans. Each appearance is unique to the place they live. No Fae tribe is like another, altought sometimes the differences might be small between one tribe and another.
