In a crisis of faith, Father Castiel calls into the dark to prove himself to God.
As Castiel spirals beneath the crushing weight of faith, shame, a hunger he cannot name, and the quiet violence of devotion, he is drawn into a dangerous intimacy with that which is most unholy.
To be truly seen, heard, and understood is divine.
Wolves are not solitary creatures. And not every fall is a punishment.
It was then that Castiel felt it: a shadow standing in the dark corner of a room, the arrested breath before a teetering chair falls back, a storm silently approaching from the horizon. Doom.
“A bit arrogant, isn’t it, Father?” Castiel jumped at the deep, resonant voice from the back of the church. He felt the voice in his chest, in the rumble of the stones beneath his feet, and Castiel stared at the furthest pews, where the darkest of the gloom gathered.
Yet Castiel stared, and stared, and stared at that spot, where the darkness and the absence seemed to hide a shape. His breath stuttered in his throat, the hairs on his neck rising as he looked and realised, with a profound, terrible understanding, that something was staring back.
Castiel squeezed his rosary, a breathless prayer falling from his lips as his back hit the marble altar.
He watched in horror as the shadows began to glide from the pews to the centre aisle, the candles; one by one, eaten by the creeping void. A yawning, monstrous eternity, the lonely and bitter universe a wall of gloom that slowly, as if lethargic by its own existence, crawled towards the priest. A chorus of whispers echoed in the dark, hushed and reverent. Tendrils of shadow slithered across the windows, the twilight of the stars, saints and archangels all consumed in its cavernous maw. The world turned dark, grave-silent and death-cold, the darkness had shut the outside world from the view, and the only things left were It and Castiel.
“To pick a fight with a fallen angel?” The creature's voice rumbled, like a thunderstorm in the distance.
