It was a stormy night, November 2nd 1979. A young couple, Zachariah and Melly Novak, had just gotten married 3 months earlier and were already talking about kids. They were deeply in love with the idea of having a family and raising children in their tiny farmhouse in the middle of practically no where.

A storm set in around 11:30 pm, thunder and storm clouds brewing in the distance making their way towards the farmhouse. While the Novaks slept peacefully, 3 miles away from
their home, a strike of lightning struck the dry ground. Anyone 100 ft away or less would have instantly died due to the horrid cracking noise and white light but the figure standing in the middle of burnt circle of grass was perfectly unharmed.

Another crack of lightning struck the ground 10 ft away.

"Hello Michael." A woman stepped out of the second burnt circle of grass and stared at the first figure.

"Anna."

"I have him."

The figure, Michael, turned with brooding eyes and smirked harshly at Anna.

"Really."

"Yes."

He walked closer to Anna and sighed. "Are you sure it's him?"

"Yes I'm pretty damn sure Michael."

Michael gave her a look. "You are close to blasphemy Anna darling."

Anna snapped her fingers and in her arms appeared a small bundle. She moved a part of the blanket away and a pale face peeked through.

"This is the boy. Castiel."

"Well." Michael pointed towards the direction of the Novak's home. "That is the family who will be watching over him until he is old enough to be given his wings and halo."

"Mustn't he be guarded?"

"Until the demons or Crowley gives us a reason to guard him. Now go."

Michael flicked his hand and Anna disappeared.

~ 16 years later ~

As Michael sat upon his throne the doors of the grand hall swung open and his head snapped over to see a dark figure striding into the room.

"You called for me Michael?" The gruff voice was smooth, yet dripped with a sense of humor and sexiness.

"Yes. We have an... Issue."

"Okay..?"

"Dean." Michael gritted his teeth.

Dean Winchester was one of the best fighters in the 34th Garrison but kept to himself. He didn't play by the rules and barely listened to any other angel but they needed him. In the late 1960's Dean Winchester had been an amazing teenage Hunter and fighter and the Angels gave him a choice- either he could live his life fighting then die a hero or become an Angel and join their forces. Dean chose the latter and had been an angel ever since, stuck at 20 years old forever.

Dean sighed.

"Have you ever heard of Castiel Novak?"

"Uh no."

"He is the son of Ezriel, the Nephilim."

Dean didn't answer and Michael sighed again, pinching the bridge of his nose.

"He is the one who will stop Crowley from taking over our kingdom, Dean."

"Oh ya, cool, so what's the issue?"

Michael stood up from his throne. "We believe that some of Crowley's minions have started to suspect that he is the chosen one. But since he is being kept in the dark about all of this until he is of age, he needs some protection."

"What does this have to do with me?" Dean asked, leaning against a pillar.

"We need you to be his guardian."

"What!?" Dean's bright green eyes went wide and he stepped forward. "You're ,pushing me down to guard duty!?"

Michael smirked.
Finally he was pushing some of Winchester's buttons.

"Yes. You are now Castiel Novak's guardian angel. We'll figure out details tonight and you'll be going to his Highschool so you can keep an eye on things."

"You are kidding me."

Michael blinked.

"You're-you're KIDDING ME."

"Dean. Castiel will be one of our most important soldiers in the war. It's in his blood and he needs to be kept safe. Also, this would give you a huge rank-up."

Dean looked up quickly at the last part. "Really?"

Michael smiled. "Let's see how you do."
