I do not own anything related to Supernatural.

This idea has been stuck in my head for weeks and won't allow me to work on my other stories lol. This is a mixture of many inspirations…from fanfics, books, movies etc. If you have any questions I'll gladly tell you where I got my information/idea from.

Note: Many of the terms I use are Gaelic/Celtic

Warnings: Slash, abuse, dominate, submissive, mpreg, knotting, violence…I can't think of anything else lol.

And Enjoy!

March ~ Moon of Winds

Castiel sat on his bed, his long fingers fidgeting with the edge of his sweater. It was finally the night of the full moon and his wolf could barely contain itself. They would be leaving soon to make their way to the Winchester's land. He absolutely loved it there, all the trees, hills, rivers…it was a playground for his pack. When it rained, he loved hiding out in the small caves near the river, his twin and his brother Gabriel often hiding away with him.

Charles Novak the Alpha of their family…their clan had become allies with the Tillamook Pack long before he was even thought of. Only three of his siblings had been born at the time. Their father was a little skittish for an Alpha but he was theirs nonetheless. Before, they had been lone wolves living in Louisiana. For whatever reason, Chuck made the decision of moving the entire family to Oregon to become allies of one of the largest packs in America.

The Tillamook Pack had been around for nearly over 400 years consisting of three clans…The Campbell's, The Singers/Harvelle's, The Winchesters, and the Novak family becoming the fourth. The founders were the Winchesters…claiming the Tillamook forest as their hunting grounds and as their pack grew, so did the importance of keeping the forest shut away from humans. The Forest Center was founded and it helped with keeping the humans at bay when it came near to full moons.

Chuck had become the financial advisor and lawyer to John Winchester, proving himself worthy and desirable to the entire pack. Though, John would have accepted them anyway. Chuck brought a lot of pups into the pack…Michael and Lucifer who were Alphas, and Balthazar was a Beta. Soon after Gabriel, a Beta was born and then the twins…Keelie an Alpha and Castiel…the very first Omega in the Novak line. When Castiel had finally manifested at 15, Chuck had been extremely worried. He had tried to keep Castiel out of the runs but John settled his fears with a warm smile.

"Chuck…we treat each other as equals…yes everyone has their place to help our pack thrive but your son will never be treated with cruelty or forced into anything he does not want. My great grandfather instilled into this pack that Omegas are not just breeders or things to release anger on. That…and my soul mate…my Anamchara…is an Omega…you have nothing to worry about my friend."

The anxiety was still there when Castiel ran for the first time after manifesting…especially when the month of the Claiming Moon arrived. It was a time when any unclaimed wolf could announce they were ready to take on a mate. Whether it is a rogue or lone wolf family, they would run, and any free wolves would chase and claim. It scared Castiel to death…he'd heard about other packs where Omegas would be knotted during the Claiming Moon without their consent. No matter how much everyone tried to reassure him, he still wouldn't leave his twin's side.

Now he was 18 and couldn't wait for the run. They could shift at will but there was something much more powerful on the full moons with his entire pack surrounding him. It had taken a while but he never felt safer.

"Hey pup! Are you ready?" His twin Keelie asked barging into his room. He looked over and smiled, reaching out to pull on her long braid. They were nearly identical…both of them had dark messy hair, big bright blue eyes and soft plump lips. They were the same height and had athletic builds but not overly muscular. As much as their physical traits were the same, they were opposites in personality. Keelie blamed it on her being an Alpha but Castiel just smiled at her. Out of all his siblings, he was the quiet reserved one. Michael had his moments where he was serious but even he would join the others in their antics. Castiel was more than happy observing them from a safe distance. He loved all of them but he was closest to his twin and Gabriel.

"Yes…it's been so long since we saw everyone," He said softly looking down at his hands. 6 months…it had been 6 months since the Novak's had joined their pack in the runs. Keelie sighed heavily and wrapped her arms around him tightly, letting him breathe in the comforting scent that surrounded her. She smelled of home, the forest, rain, and orange blossoms. Whether it was the Alpha in her or not, he loved being close to his twin, she always knew how to make him feel calm…safe. He knew over the months he had become clingy, craving to feel the protectiveness that would pour out of her when he got like this.

It got even worse when he was consumed with missing their father…he had been such a great man…loving and attentive. He always made time for each of his children no matter how busy he would be. And now…he was just…gone…ripped viciously away from them.

They had been getting ready to head out to join their pack in the run…it was going to be so much fun…the month of the Singing Moon was always joyous. On their way out, a rogue wolf attacked them outside their home, ripping their father's throat out. His alpha brothers attacked and brought him to their Conri. Keelie tried so hard to keep Castiel calm the entire way their but he couldn't breathe through his sobs. It took the touch of his twin, Gabriel, Balthazar and even Lucifer to finally calm him enough to stop hysterically crying.

When they arrived on the land, it seemed as if everyone just knew what had happened. Michael carried their father while his other brothers dragged the rogue to their circle where John was waiting. Castiel clung to his sister his legs just barely keeping him standing while their mother stood behind them not saying a word.

John threw his head back with a loud howl as he was consumed with grief, demanding the rogue's head immediately. Bobby Singer, his second, dealt the killing blow without hesitation. Instead of a joyous night…they burned their father in the circle of moonlight, their entire pack raising their heads in a joined howl. Their family was still trying to cope…the oldest, Michael was now their Alpha and trying his hardest to take on what his father left behind. Quickly agreeing to renew their alliance with John…even though their mother, Naomi, was against it. He still never understood why but he tried to not dwell on it too much.

"I miss him too Castiel," his sister whispered against his hair. He took in a deep breath and let it out slowly.

"We'll run for him tonight…" He said giving her a small smile. She returned it and grasped his hand in hers.

"That we will…now come on, everyone's going to be there tonight. John's going to accept our brother's new alliance and Dean's going to be naming his second!" Keelie exclaimed and Castiel felt his cheeks burn at the mention of Dean. Keelie stared at him for a moment before giggling.

"Oh my poor twin…will you at least try to talking to the poor boy instead of running away this time?" she asked with a smile. Castiel just huffed out a laugh before getting to his feet. Dean Winchester was the object of many…ok ALL of his fantasies. He was perfect…beautiful, smart, charming, an amazing Alpha…he was going to make his ancestors proud when he became the new Conri. Even his wolf form was perfect. A dark sandy brown and he was huge, the size of a horse. His amazing Jade green eyes would become brighter…glowing against his dark fur when he was in his wolf form. Castiel still couldn't believe that Dean was nearing 19 and still hadn't taken a mate…what the hell was he waiting for?

Almost every female of their pack wanted him…anytime a lone female wolf would join their runs, they always tried to make a pass at him but Dean always rejected them. Every time…

It wasn't like he didn't have time…they were not immortal but the aging process would end when they reached 18 and then it would rapidly slow until for every ten years, they would age maybe one or two. Normally with Alphas…and especially heirs, they would find their mate…or their Chroi's before then.

Many of Castiel's fantasies consisted of Dean claiming him as his Chroi…his heart and mate…but of course, he'd wake up to reality. A reality of which he was a simple little Omega who could not offer anything of value to the amazing wolf that was Dean Winchester.

"Castiel…why are you still afraid to talk to Dean?" she asked and Castiel didn't need to see her face to know what she was thinking…or feeling for that matter. True twins didn't happen very often with their kind…especially ones like himself and Keelie. They could link to each other through their minds and even feel the others pain or emotions.

"I'm not afraid…just…he…ugh…he makes me nervous and I become this…stuttering mess around him," he whined and pulled out his trench coat from the closet. She snickered and helped him straighten it over his sweater.

"You wear way too many layers twin…come, Balthazar is probably finished packing the jeep," She smiled tugging at his hand.
