By Heaven's Design => Part 1: HEAVENSENT
-> gabriel (spn) x reader, other characters
Summary: «As it is in Heaven, so it shall been on earth.» When Gabriel said this, it was to give a warning. Yet, he never imagined those words would come back to bite at him as well. There was only one rule in Heaven that stood above all else. Even more than war and obedience: nothing stood between an angel and its mate. It was a celestial law, a duty, one of the most undeniable among his kind, something he hadn't thought about ever since he left Heaven, his brothers and everything he was created for. When he realized a common human girl could see his wings - mistaking them for cosplay, no less - he knew he was doomed. Mating wasn't romance. It was rare and sacred, it happened only once in the existence of every angel and it lasted for all eternity. But Gabriel found so much more than his mate. He found the center of a celestial design that was never just about Dean and Sam Winchester, but also about a girl that mirrored him too closely, whose soul fit his grace too perfectly and with a family that seemed normal, but was actually the key of a prophecy older than creation. And he would do what every angel would do for a mate: whatever it takes to make sure she remains unharmed, no matter the cost.
Warnings/content: Basically an introduction of the first part of the fic since it's divided in two. A bit of my take into the angelic mating lore. Might be confusing at first, but it will make sense, I promise!

Even though it is said that every angel has a mate, finding them is an entirely different kind of matter. And when they do, everything changes. Mates are rare. That is why they are sacred. They are among the most treasured things in Heaven, and also the most feared. Bargained over by enemies and fiercely guarded like holy relics. Even when they're human, their value is impossible to be ignored. A mate becomes, and always would be, an angel's entire world, which makes them their greatest strength and their deepest vulnerability. Their only weakness. There is no middle ground. Angels will choose their mate over Heaven. They will choose them over everything else: over the Host, over war and duty, over any divine order ever given, even over their own existence. Because mates are not destiny. For angels, they are inevitability. Angels do not simply fall in love, they recognize what was always meant to be theirs: their soulmate, their charge, their... one and only. The moment a mate is found, the very purpose of an angel's creation reshapes itself around a single soul, the one they're bound to protect, mark and claim. The one they were always sworn to. A mate makes an angel unstoppable. Grace turning feral with territorial instincts, something ancient awaking beneath celestial obedience. Something powerful enough to make even the Father itself hesitate. Touching a mate means inviting the worst kind of Heaven's wrath upon your head. If harm comes to a mate, even the stars will tremble. An angel's grace can sense the pull of their mate's soul long before their voice is ever heard, before wings recognize them and before human eyes ever understand what they're looking at and why their souls respond so vividly. Angels were made to defend souls by design. And a mate's soul, the one they wait for since the very first moment of creation, is untouchable. A human who binds their soul to an angel's grace and bears their name marked permanently on them does not remain entirely mortal. Time loosens its hold on them, aging falters, then stops altogether, until they remain standing beside their angel almost unchanged by years flowing upon them like wind. Immortality is not the gift. Forever together is, and sometimes it comes with a price. Blades, fire enemies or fate may still claim them. If a mate dies, an angel does not mourn. An angel breaks. Sanity dissolves, every rational thought disappears. Grace reacts violently, driven by a single instinct: vengeance. The world must burn first and then, only after the debt is paid in blood, does the angel follow their mate into Heaven permanently, abandoning the world they once served. History remembers wars. The Bible records them. The heavens remember the angels who started them. An angel who is mated will stop at nothing. And that alone should be a warning enough. Archangels themselves are not exempt from the laws of creation. The first four angels ever created, the only beings who saw the face of the Lord. Ancient and absolute, they are Heaven's most powerful and terrifying weapons: fierce and dangerous beyond measure. And even they were not immune to the call of the soul that belonged to them.
One of them, especially, absent from heaven's watchful gaze for millennias, had long stopped waiting. Had long stopped searching. Until the day he found his mate and discovered the world was already trying to kill her.
The Bible knew him for delivering messages.
The other angels knew him for running away.
Pagans knew him for tricking mischief.
His mate would know him as the only angel whose six golden wings she could always truly see.
And together, they would earn their forever.
