A/N Hellooooo reader! I apologize in advance for the short intro chapter, but I think you'll thank me later :) This is the tale of a mythical Phoenix who comes into the lives of our favorite brothers, joining them in their quests, much like Castiel (who will make cameos in this story, I promise!) to aid them. Much of the lore on Phoenixes are of my own creation (mixed along with what they show has mentioned), as well as different mythological beliefs and lore. I do NOT own Supernatural or anything affiliated with it. If I did, I'd be having this Phoenix on that show. Oh yeah, baby. Enjoy the read and R/R!

They say Phoenixes are born of Heaven and Hell… that they are the offspring of a volcanic eruption when it kisses the skies. In many ways, firebirds are angels –and demons- in their own light. They spread wings to fly, but breathe fire to burn. They need a vessel when they are not in their true form, and their powers are many. For millennia, Phoenixes have just been a myth, a legend for hunters. There weren't any erupting volcanos strong enough to have touched Heaven during an eruption… until Hell festered with one in aims to burn Heaven to the depths. Instead, the result was a fantastical creation of a beautiful bird blessed by God and cursed by Satan. Thus, the first Phoenix was born.

For thousands of years, it slept. It slumbered in the darkness of the volcano it was created from, content to wait until it was time to wake. It was the year 400 B.C, off the coast of the volcano's deserted island, of which to the day it remains elusive to humans and the supernatural alike. A ship was sailing in a storm, the volcano festering in the Phoenix's impatience. On the ship, members of an ancient Celtic royal family struggled to stay aboard and survive. But it was not to be. The oldest daughter, the princess Gwencalon, fell overboard the ship into the swallowing waves, carried far away from the ship, which later sank. The young princess washed up unconscious on the shores of the island, where an ancient islander tribe resided. They knew of the legend of the volcano and the Phoenix that slept within, and by the rumbling of the earth and the bursting of magma from the volcano, they knew it was time for the Firebird to awaken.

They took the Celtic princess and brought her to the volcano, where they chanted and danced and offered her as a vessel to the rising force. They witnessed as the lava boiled, bursting until a great swan with the most beautiful plumage and wing span flew from it's bed, flying around the volcano until it saw the girl. The Phoenix accepted the offer, and dived for the human body, the bird changing into light rays that filled the human body with light and flames, the body falling into the magma, until it burst from the heat and flew into the heart of the volcano. The body transformed. The girl's once brown hair become long and as scarlett as blood, her skin fair and lovely, her eyes as purple as the cosmos above. The tribe watched in awe as the Phoenix floated and descended to them, falling to her feet and worshipping her.

But she bade them not, beckoning them to stand. They watched as she strode within the middle of the crowd, admiring her new vessel. She kept most of the princess's features, the vessel having been enhanced to fit the Phoenix's personality. She was beautiful and fierce, gentle and just. But as the Phoenix looked ahead to watched the distant setting sun over the horizon of the blue ocean, she could only smile. She glanced to the Heavens and down to Hell, knowing exactly where she came from, and who she was.

But the Phoenix did not know only one thing. What was she supposed to do? What was her purpose here? Until she knew, she'd wait.

And wait she did.

For over two thousand years.
