Thor's hammer and other heavy objects

Chapter 1

Dean opened the trunk of the Impala, and wrinkled his nose at how messy it was - it could really need a serious round of spring-cleaning. They had been throwing things in there for way too long without tidying up. But now that Castiel had come back from purgatory, Dean had regained a bit more peace of mind; and it seemed high time that he focused on making his Baby presentable again.

He began by removing all of the trash, and tossing the various spare parts in couple of plastic bags. He picked up their duffle bags and the bags he just filled, and carried them to the motel room where he and Sam stayed for the moment. They where hunting an exceptionally infuriating demon which was harassing the town they where staying in.

Sam looked up from his computer when Dean entered with the huge load of bags.

"You planning on staying permanently or...?" Sam asked.

Dean threw all the bags on his bed.

"Thought it was time we cleaned up in some of the crap we've gathered." He answered.

Sam agreed; it wasn't a bad idea - it wasn't like they had any notions on how to stop the demon right now anyway. He shut his laptop and went over to help his brother with the sorting. He seated himself on the edge of the bed and began sorting through a plastic bag, while Dean went through a duffle bag at the foot of the bed.

The bag had been heavier than the other ones, and Dean was excited to see what was in it. Of all the things he had expected, a huge hammer with strange engravings definitely wasn't one of them. He had seen the hammer before, at the monster auction they had been to with Kevin. It was Thors hammer.

"What the hell, Sam?" Dean asked and lifted the hammer - it was heavier than it looked he noted.

Sam frowned. "Shit, I had completely forgotten that."

"You forgot that you put Thors hammer in the trunk of my car? How is that even possible?"

Sam shrugged. "I thought it was irresponsible to leave it in the hands of those thugs, so I took it. But since then we have had a lot of things on our plate, so I hadn't really thought about it."

Dean realised that Sam had a point, but what the heck was they supposed to do with it?

"So, what now? What do we do with it? I don't know about you, but I don't exactly S.H.I.E.L.D on speed dial."

"Maybe," Sam hesitated "maybe we should deliver it back where it belongs, you know in the Viking Age. Cas could probably do it."

Dean didn't care much for the idea. He wasn't sure if Castiel was back at full strength jet, and he knew that time travel usually took it's toll on the angel. But if Castiel should only transport himself and the hammer, it wasn't sure it would be quite as hard on him, as if he should transport all three of them. So he called Castiel, and a few seconds later the angel was standing in their room.

"So what do you say, Cas? You think you can do it?" Dean asked after he had explained Castiel the situation.

"The further back in time I have to go, the harder it will be. But it is possible." Castiel answered.

They all approved of the plan, and agreed that Castiel should go. Nevertheless Dean wanted him to hurry back afterwards.

Just as Castiel was about to place his hand on the hammer, the door was flung open and a thick black smoke; that was definitely demonic, filled the room. But before Dean could even react, he felt the uncomfortable; but jet familiar, feeling of being teleported. Next he knew; he was standing in a forest, watching the demon slither away into the shadows of the trees.

Dean looked around, and quickly spotted Sam - who seemed to be okay, standing close by. Then he noticed Castiel who was lying motionless on the ground.

"Cas!" He said, while he rapidly sat down beside his friend. He tried to wake him, but the angel was completely wiped out, but at least he was still breathing. The hammer was lying beside him.

"What happened?" Sam asked confused.

"Cas probably tried to save us from the whole demon situation, by zapping us with him." Dean answered as he looked up at Sam.

Sam sighed. "Yeah, but he also took the demon with him.

"Yeah, and so what? It ran off, we'll find it soon enough. Besides a demon is the least of out problems right now." Dean replied, as he once more watched the unconscious angel.

"Dean, you know I didn't mean it like that…"

"Where the hell are we even?" Dean interrupted him.

Sam shook his head in defeat. "I don't think it's the right question to ask where we are, but rather when we are."

Shit. Sam was right, Castiel wouldn't be knocked unconscious like this, if he had just zapped them to the nearest forest. No, they had definitely travelled back in time - way back in time.
