I actually had to go digging around for these notes from about a year ago XD I have put thought into this several times before.
((Don’t worry! Castiel is still in Brothers Apart and will run into the brothers soon, so none of this is saying she replaces him!))
Directly from notes:
Of the fairy realms, there are three:
Aeternum of the gods,
Avalon of the Seelie,
Pandemonium of the Unseelie.
Avalon, for the fae, is their realm of heaven. Here dwells the Summer Court and the good fairies. Beware making deals even with the good fairies, they will ensnare the unwary in their webs and bring them to their home to service the king.
Aeternum of the gods is the purgatory of the fae. The guardian sprites live within, closer to the human realm than the others. They will attend a summons for help, keeping the balance of nature as commanded by their creators.
Pandemonium is where the Unseelie live and where the Winter Court dwells. The fairy version of hell and where their devil reigns. The fae that live within are wicked and quick to anger, often declared outright evil, though much like demons there are shades of grey within this truth.
(All of this is true in the Brothers Apart verses, not necessarily the Supernatural show. I took their lore and expanded it)
All this being said, the elemental sprites are some of the strongest of the fae, and because of that they were sequestered to the purgatory of their people, where the world remains unchanging and they can tend to their separate elements and bind any dangers to the other realms to guard over. The Midas amulet being only one of those dangers.
They are close to the leviathans, but without the innate evil and desire to consume the world.
Most aeternum sprites chose to ignore the rest of the worlds and keep to themselves until summoned by their gods to attend to their given tasks.
Nixie is an exception, but thankfully not the only one. We’ll have another sprite like her showing up in the BA verse to help make atonement for what the fire sprites have wrought.
Aww, I’m so touched to hear you love my writing so much! ❤
