Dimensional Portals are Annoying

Chapter 1: A Long Way to Travel

Clop, clop, clop pity, clop, clop. The sound of horses' hooves echoed against the dirt. If one looked, they could see two indistinct shapes mounted on the road. On closer inspection, the two shapes were really men wearing camouflage cloaks. They were also both wearing double knife scabbards and each had a strung longbow on their laps and a full quiver on their right shoulders. Should one come close enough to see them, they'd realize that the cloaks' hoods were up, obscuring their features. They were also very short. Their horses were short but stout things and very shaggy.

Once they reached a fork in the path they stopped. The older man looked at his slightly shorter companion and asked, "Will, take a look and tell me what you see."

The other one, Will, dismounted shaking his head. Even though it was years after his graduating to be a full-fledged Ranger, Halt still treated him a bit like an apprentice.

He carefully bent down to one knee to study the tracks left behind by their quarry. They were tracking a missing person, multiple in fact. People had been disappearing in Redmont Fief for a few days so far. They all were going hiking when the disappearances happened. So far there were no other connections between them. The only reason Halt was with Will was for company. After all, it should be an easy mission.

The tracks indicated that a lot of people had recently been traveling the right fork. One detail in particular caught Will's attention. There was a small thread snagged on a bush. It was yellow. This told them they were going in the right direction. After all, one of their missing persons was the only one who wore yellow regularly.

Will stood and told Halt his inferences, "They went down the right, judging by the tracks there and by the thread snagged on that bush. One of our quarries is notorious for wearing yellow a lot."

Halt also dismounted and looked around. He soon straightened back up and nodded, "You're right. They all lead to that forest down there." He said grimly.

They both mounted back up and rode to the right. Once they neared the forest, they noticed something strange; there were no tracks in the forest after a few meters in. Halt and Will reined up and scouted the edges of the forest. There was no sign to indicate someone had backtracked and gone around the side.

Halt then dismounted and took a piece of parchment and some ink and quill and wrote quickly. Don't enter this forest. This is where people are disappearing. Will and I are going to investigate. He finished by signing. Ranger Halt.

Halt then laid down the paper on a rock and picked up another to weight it down. That done, he spoke to Will, "Careful Will, something is going on that we don't know about. We need to be cautious."

Once Halt mounted, the two rangers carefully made their way into the forest. Once inside a few meters, they reached where the tracks ended. They soon rode over them after examining them. That soon turned out to be a big mistake. Their feet and their horses' hooves, never reached the other side.

Instead, they rode into a new place and promptly swayed in the saddle, falling out and fainting. The two shaggy horses also fell, albeit more gracefully and with more control. They laid down and stayed by their masters' sides.

Shield HQ 15:22

Ping, ping, ping, the machine signaled for the fourth time that week. Another anomaly had just occurred, an anomaly that allowed people to cross between dimensions. For the past week, these had been becoming more common. Throughout Shield HQ it was hypothesized that this was all Loki's fault. It seemed he was opening portals from other dimensions to this one. They all happened in different places. Luckily, this one was nearby. They could actually get to this one in a reasonable time.

Nick Fury, director of Shield, sighed. They had to at least make an effort to visit the anomaly sites. For all they knew, it could be Loki leading an army of the Chitauri again. After issuing some orders, Fury and a few shield agents got in a helicopter and went to greet the new arrivals. And access if they were a threat or not or if could help them.

Once arriving, the Shield agents looked around. They quickly took in the sight of two strange men in strange clothing sprawled on the ground unconscious with horses standing guard next to them. The agents also noticed the two strung longbows on either side of the new arrivals. However, when they approached to take them, the two small horses whinnied and looked at them, giving them the impression that they were saying, Don't you dare. Whatever happened, the men soon backed off.

A/N I would appreciate it if someone would beta for at least the Avengers' part for me. I've only seen the movie once. Thankfully, I've recently read the Ranger's Apprentice series so Will and Halt should be more or less characterized correctly. Please tell me if this is a good idea for a crossover and if you have any suggestions for the crossover, than please suggest. Thank you for reading. Also, don't hesitate to point out flaws in grammar or cannon please.
