I'm at work, so quickly dropping in.
Faeries are man-made elementals bound to the soul crystals of Nymian scholars. So the soul crystal is kind of a requirement. It's how faeries have memories and maintain their personality over the ages, even when summoned by a new scholar. Compare this to modern carbuncles who, despite being made from the same few gemstones, exhibit ranging personalities depending on the individual caster.
I've put together a post that outlines the role each individual soul crystal plays in it's respective job here!
More lore on the different schools of magic and their aether sources can be found here!
