Earth

It had taken three months but Shield had finally managed to get Thor's attention, he had ignored them when they asked about helping with the Ten Rings or Hydra, Thor had felt that his new Avengers friends could handle such matters without his help. He decided to make up for lost time with Jane but his newest call for help caught his attention mainly because Coulson had brought him a picture of what they were going against.

Now here Thor was riding a Quinjet into a hot zone as Coulson had called it. The beings attacking the Shield outpost were humanoid and wore black and beige armor and were using some sort of energy weapon Shield had never encountered. "Those are Dark Elves" explained Thor prompting a chuckle from Coulson.

Thor looked at Coulson with confusion at the possible joke he missed and Coulson waved him on. "So, what do these Dark Elves want?" he asked, Shield had been on high alert ever since Loki had attacked three months ago.

"The Dark Elves have been fighting a war against the Light Elves since before I was born. They seek to take the Light Elf home world of Alfheim for themselves but Asgard has always been there to hold them back" explained Thor looking at the picture of the Dark Elf.

"Well unless I'm lost this isn't Alfheim so what would they want with Earth?" asked Coulson as they were approaching the landing zone.

Thor picked up Mjolnir, "I intend to find out" he said as the door opened and he flew himself out into the open air and into the battle.

There was about fifteen Dark Elves on top of a hill using energy weapons to fire down on Shield agents and local authorities. Thor landed among them and deflected energy blasts using Mjolnir. "Get to cover" he ordered before launching up the hill towards the Dark Elves.

The elves started shouting in Elvish as Thor moved in a delivered a few blows with Mjolnir, he turned towards others noticing their uneasiness. "Tell me how you came here and why and I will allow safe travel back to Svartalfheim" he offered wanting to get to the bottom of this whole situation quickly. The handful of Dark Elves still standing looked at each other and spoke in Elvish. One in the back nodded and turned to run while the others began to attack Thor.

Thor cut them down with ease and chased after the escaping Elf and quickly caught up to him using Mjolnir to pin him to the ground. Thor moved up towards the struggling Elf and looked around "Where were you headed?" he asked not seeing anything. He looked at the Elf, who was staring into the distance like he was looking at something. Thor looked and picked up a rock and threw it in the direction the Elf was looking and was shocked to see the rock bounce off an invisible ship.

The ship decloaked and its black exterior was revealed, it was shaped like the letter T. Thor had seen these ships before but he had never seen the cloaking technology up close before. The ship was much smaller than the ones that could be found on the desolate plains of Svartalfheim, leading Thor to assume it was a scout ship. Thor turned back to the Dark Elf, "What are you doing here?" he asked hearing Coulson's Quinjet coming closer to his location and Shield agents forming a perimeter around the area where the fighting occurred.

The elf spat something in Elvish and Thor shook his head "Speak common tongue and I will let you go" Thor promised prompting a strange look from the trapped Elf.

"We were sent to investigate Midgard and assess its capability to fight back against us and report back" explained the Elf prompting Thor to lift Mjolnir off his chest and allowing him to stand up.

"Who sent you?" asked Thor hoping to get some more out of the Dark Elf when suddenly another much larger Dark Elf ship appeared. A large figure leapt from the ship and landed next to Thor and the Dark Elf. The large beast delivered a kick to Thor sending him flying before turning its attention to the Dark Elf.

"Please Kurse, I wasn't going to say anymore" the Dark Elf begged before Kurse grabbed him by the head and shattered his skull.

Thor stood up and looked Kurse over, he was much larger than any Dark Elf Thor had ever seen, his skin was hard and dark with horns sticking out at his shoulders, knees, head, and face. Kurse made sure the Dark Elf was dead before turning his full attention to Thor. Kurse towered over Thor with dark red eyes that examined the God of Thunder.

"Who the hell are you?" Thor asked as Kurse seemed to be contemplating his choices. Kurse started to walk towards Thor when a blast from the ship landed near Thor sending him flying backwards and away from Kurse. Kurse chuckled and leapt into the air landing on the ship that quickly flew into the atmosphere and away from Earth.

Thor stood up as Coulson and his Shield agents approached him, "What the hell was all that about?" asked Coulson as his agents were collecting the bodies of the Dark Elves and their equipment.

"I don't know but it wasn't good" Thor explained contemplating his next move. "They said they were testing the Earth."

"Testing huh? That never goes well for the ones being tested" stated Coulson as more quinjets arrived.

"No, it doesn't" replied Thor sighing and making his way around to inspect the Dark Elves equipment.

"What would they want with Earth?" Coulson asked trying to get as much information as he could from Thor to report back to Fury who was currently organizing several other operations.

"The Dark Elves home world is a called Svartalfheim, it is a dark world in a dying part of the universe, there is only so much time before Svartalfheim is destroyed. My father always said that was what started the actual war between the Dark and Light Elves, the Dark Elves needed a new home and planned to take one in the form of Alfheim. If they feel that taking Alfheim is too difficult, Earth would certainly make for a reasonable replacement" explained Thor standing and looking up into the sky where the ship vanished. "They haven't managed to figure out Bifrost travel completely but those ships of theirs would certainly get them where they need to go."

"So, first an angry Asgardian opens a portal showing the Earth to anyone lucky enough to be in the general vicinity and now all of a sudden Dark Elves have decided to turn their attention from a war they have been fighting a long time to us. That doesn't seem like a coincidence to me" remarked Coulson pulling out his phone to dial Fury. "So now what do we do?" he asked so he could give a recommendation to Fury from Thor.

"All of this means that it is time for me to go home" answered Thor spinning Mjolnir and launching himself into the air leaving Coulson behind.
