Author's Note: I don't know how the heck I came up with this plot. I blame tumblr, the fandoms, and my brain for the cohesion of fandoms. I also haven't actually posted on in a long time, so forgive me for reviewing the process of using this site again. As for chapters, I will try to post 1-2 a month.

Disclaimer: The Avengers belong to Joss Whedon/ Marvel and the world of Middle Earth belongs to the genius, J.R.R Tolkien.

Rating: Will stick to T for now, may go up higher in later chapters.

Walls Around the World: It must have been one of the side effects of the drugs that Stark had inserted into her, because she could have sworn that the stars seemed bigger than normal ...Avengers/LOTR .Eventual romance, but not your average fairy tale. They have a lot to overcome, and a lot to learn.

Timeline: Pre-Hobbit.

"Natasha?! "

The Avenger blinked.

"Natasha….!"

Where was she?

"Agent Romanoff do you copy?!. . . Damn it! I thought you . . !"

The voices faded into static, and with it came the sinking feeling that she was alone in the dark oblivion. She flexed her muscles with enough energy to reach around her, and with a jolt realized that her hands were touching grass and dirt. She didn't remember there being any in Stark's lab; he was too OCD to allow any of that into his lab. Slowly, she raised her head and couldn't help but shudder as an owl hooted overhead. Nat let a groan when she quickly came to the conclusion that she didn't have enough stamina to do a thorough inspection of her surroundings just then. It didn't help that her shoes felt like heavy bricks of lead clamping her down. Wherever she was, it definitely wasn't Stark's Tower nor anywhere in New York that she could recall ever being in. Briefly, she wondered if this was how Steve felt after waking up from coma.

She tried dragging her knees up with her feet still on the ground, but was only able to lay on her back awkwardly staring at the stars. It must have been one of the side effects of the drugs that Stark had inserted into her, because she could have sworn that the stars seemed larger than what was usually normal for a September night. Maybe Thor would know them since he was a god after all, she mused.

At some point, she drifted off into a dream. Her only comfort were the knives tucked underneath her shirt.

The itsy-bitsy spider…

The Necromancer wasn't content with the current situation. The glitch. It wasn't supposed to happen. Someone had gotten in the way, and they had positioned the arrival spot miles away. Too far away for him to travel without any of the Blue Wizards knowing. He needed to send the message to one of his special servants. She wouldn't need to find the visitor just yet, no. He'd wait for that.

Right now, he'd just need to give the visitor a little nudge in the right direction with help from one of the Underlings. The Elves of Mirkwood wouldn't mind...they owed him.

She woke up with a jolt, and at first wasn't sure what woke her. But her body's cold reaction made her realize that she wasn't alone. Sometimes, her sharp instincts were her only life savers and this time, they were on high alert. Get up, damn you, she berated herself, clawing at the ground to lift herself up. Awkwardly, she flipped over and almost wished she hadn't.

She clamped her mouth shut, refusing to scream but her eyes widened regardless. Dozens of pale eyes stared back at her. The face was hairy, spiky even as it leered at her from above. The irony would hit her later, but Natasha couldn't think of any black humor at that moment. She just froze as the predator stared back at her. When its reeking breath fanned onto her face, two things happened at once. Her stomach threatened to release whatever was left inside of her, and most importantly, her legs finally kicked into her gear.

Natasha's main goal was to gain leverage of some kind as the creature obviously had the advantage of size and strength. She had been in crazy situations before, but nothing had involved gigantic creatures that had immense clippers for mouths. She didn't know what the beast was waiting for, but her eyes moved slowly to the thick tree trunks surrounding them. Although spiders could easily climb in any given situation, Natasha only needed a few seconds of higher ground to impale it somehow.

It must have been her fingers that were inching towards her hidden knives that finally made the beast move. Its' legs scurried towards her, raising it's clippers. She rolled, and somehow crashed into a tree trunk. It was then she realized that she had been on a hill the entire time. The slope managed to give her momentum as well as some separation between her and the spider. Without glancing back to check on the creature, Natasha swung onto the first branch easily enough while reaching for her knife. Nat couldn't have done it sooner as the spider barreled towards her.

Perhaps it came naturally to her with how she climbed up the tree, but she knew the anatomy of the spider well enough to avoid its pinchers both in the mouth and the bottom of its' feet which made the climb something she had to ultimately focus on. She could sense the spider calculating her next move, and it was out of pure reaction that made her arm swerve behind her. Her hand was met with an explosion of sticky netting. Natasha froze in confusion just long enough for her predator to jab one of its pinchers into her arm. She could hear Tony's laughing at the irony of the situation in her head as the Black Widow was forced to close her eyes for the second time that night. Her mind still screamed at her to hold on.

New York

"What do you mean Agent Romanoff never arrived? You said before that she was only Off the Grid!" Fury's voice bounced off Stark's lab causing it to sound louder and then it already was, and made the room even more tense than any of the Avengers would care to admit. Stark himself was shuffling around his different gizmos trying to act to like he knew what he was doing while having Pepper glaring at his back. He had only followed Thor's instructions when it came to send anyone to his Realm. Now….now, things were messed up. It wasn't like Captain America becoming President kind of messed up, it was really more like Loki terrorizing the world and letting aliens infest the world kind of messed up.

Lines and numbers skimmed across the screens as he analyzed the new data entries of Romanoff's failed trip. Once her com had gone down, that's when things had gone haywire. There was no sign of her tracker, and with that came no sign of life. But it was one of the Avengers who had gone missing. Not some low life imbecile. There was still hope, there was still possibilities that Tony Stark could-

"Tony?" It was Pepper, leaning over his shoulder like always. She was the reminder that he could always do better.

"Hmm?"

"Since when did you gain access into NASA's satellite systems?"

"Ah, that, well, you see…"

"Tony…" her voice again. He really did make a mess of this. Shit.

"It's quite easy, you see…."

"What's that noise?" It was Thor, looming down on the screens and nearly smashing one of them with his Hammer as if the computer was an alarm clock. It always made Tony tense when Thor was in any proximity of his technology. Then again, it was beeping…It was a satellite picking up more information.

Suddenly, it all made sense. The lack of no communication, why he couldn't get a sign of life from Agent Romanoff. The Galaxy wasn't part of their own Galaxy that Romanoff had landed in, because the recognitions on his systems didn't make any sense. The latitudes and longitudes weren't part of the Galaxies known to him, and Thor had a high enough IQ to tell him what was part of the Asgardian Empire. The information looked Arabic almost…. but no, it couldn't be. He let Banner work on the information, printing off dozens of papers and handing them to the other Avengers. They were directed to search for clues, anything that would make sense about Agent Romanoff's current situation. Tony was just about to hand over his resignation papers when Barton finally broke the tense silence.

"Director, have you ever heard of Middle Earth?"

Tony had known that he should have checked Barton's blood sugar.
