AN: Hi again! It's another story for everyone! I hope you enjoy it! And just a quickly note, cussing is not, and I repeat not, my everyday vocabulary. I feel very uncomfortable around it, and I'm not exactly happy that I have to use this in my story. However, the only reason why I'm using cuss words because that's in the canon characters' vocabulary. I'm only trying to keep the characters in character. Anyway, enjoy the story!

Prologue

Have you ever went against what looked liked wolves, but were bigger, had a hunched back with what looked like multiply stumps coming out of it's back that appears to be producing fog, while also having this dark, dry face with dark blue fur surrounding the rest of the body? Well, the Avengers have. In fact, they're currently fighting five of them right now.

They didn't know why a portal that strangely looked like a Bifrost portal had suddenly appeared in the Northern Forest, but it caught the Avengers suspicion when Thor said he didn't know someone was visiting from Asgard. So they decided to investigate it, only to be ambushed by a pack of Ice Wolves.

"Whoa!" Tony yelled as he flew away from a wolf tried to bite him when it jumped. "Okay! These dogs are getting on my last nerves! What exactly are they?!"

"Ice Wolves!" Thor yelled out as he continues to smack Mjölnir against the Ice Wolf he was fighting while avoiding it's attempts to bite him. "Dangerous creatures known to Asgard! Those who set off to find a pack of them, they returned with nothing but their mauled limbs sent by the guards that will find them!"

"Mauled?!" Steve Rodgers yelled as he slammed his shield at a Ice Wolf that was lunging at him. It made a loud crack, signaling that he broke it's skull and was now lying dead. "You have a really weird homeland, Thor."

Natasha was busy fighting off a Ice Wolf with a large piece of log that she found in the forest. She swung it at the Ice Wolf when it lunged at her, it only ended up between the Wolf's razor sharp teeth. Natasha tried to get it to let go, but once her bare hand touched the Ice Wolf's dry face, she yelped in pain pulled it back. There were small hints of red on her hand, a mild case of frostbite.

"These dogs are living up to their name!" Natasha growled as she manage to get the log loose and hit the Ice Wolf with it, slightly dazing it. "Don't let them touch your skin! It'll cause frostbite!"

"Oh great!" Clint groaned, as he was chased by a wolf. He ducked underneath a fallen tree and hid beneath until the Ice Wolf ran pass him. "I just came back from a mission at Rogers Pass, Montana, and I'm close to freezing again!" He suddenly yelped when the Ice Wolf found him and tried to bite him through the log, but ended up getting caught in the tree since it's head was so big.

"Why am I suddenly getting the feeling that I'm going to be involve with more chilly-related missions from now on?" Clint question himself before raising his arms defensively when two loud growls came flying by him and crashing into a tree. It turns out it was the Hulk just punching an Ice Wolf that was just chasing Iron Man into a tree.

Hulk let out a loud roar before it continued to smash the wolf into the ground, dozen of times. Once he was done, the Ice Wolf looked like it was crushed a thousand times over, even the fog that it was producing had stopped.

"Thanks for that, Hulk!" Tony called out as he flew by Hulk and began to fire his repulsors at the Ice Wolf that just pinned Thor down was planning to bite him. The attack did little damage to the wolf, but it gave Thor the distraction he needed. Getting his hand free from underneath the Ice Wolf's large black claws, he summoned Mjölnir and smashed it against the Ice Wolf. It send it flying toward Hulk, who locked it in a choke hold until it went limped. The last two Ice Wolves looked at one another, then one of them nodded to the other one, before they both fled from the Avengers.

"So Thor, you want to explain to us why there man-eating, frost covered wolves from your home are here?" Clint asked as the rest of the Avengers made their way over to Thor, who was trying to discern at what just happened.

"I have no idea, Son of Barton. Though Ice Wolves are highly intelligent pack hunters, they do not know how to cross between realms. Someone must have sent them here." Thor told them, his voice sounded disturbed as he glaze the remaining dead bodies of the Ice Wolf.

"Well, yeah, but who?" Tony asked as he survey the ground, which instead of the usual Bifrost markings that happened when someone is transported from Asgard to Earth, there were markings that looked like a giant snowflake. "'Cause it seems like who ever summoned them, they sure do like the cold. And I know for sure Thor's father is the last person to like the cold."

"We'll worry about that later," Steve said, "Right now, what we need to worry about is that the Ice Wolves brought something with them, and two more are still out there." He turned to Thor and asked, "Thor, do you recognize the object they brought?"

"If I were to guess, I'd just say a regular Asgardian Urn." Thor shrugged. "They hold no value but storing drinks and ashes."

"Well, they brought it here with them, so this urn must have some value." Steve told him.

"Speaking of which, where is that thing?" Clint asked, causing the rest of the Avengers looked around at the ground. "It couldn't just disappear from thin air."

Before they could continue their search, Natasha suddenly yelped out painfully while grabbing her hands that touched the Ice Wolf.

"Nat!" Bruce called out, who had just returned back to his normal form and hurried over to her. "What is it?" He saw her holding her hand and took a look at it. Once he saw how waxy Natasha's hand got, Bruce's mouth dropped open. "Oh my god... Her frostbite is just reaching it's superficial stage!"

"That's what the fog is for," Tony realized after JARVIS just finished scanning the fog. "Guess those snow puppies can't stand the cold, so they produce the fog from the liquids inside of them."

"Liquids?" Steve asked, not understanding much about modern physiology.

"Basically saliva, mucus, blood, and stomach acid." Tony summarized, before grimacing. "God, mucus? These are by far the grosses creatures from Asgard that I ever met! And I'm just realizing we're standing in the middle of a mucus fog, I'm out!" With that, Tony flew to the jet that they arrived in.

"Okay, come on, Nat, come on." Bruce mumbled as he helped Natasha up and began to lead her to jet. "We'll get you warm up. Come on..."

"Hey, wait for me!" Clint called out as he hurried after them. "I'm going to need that warming up treatment after going on two winter missions!"

Steve shook his head at the act of ingenuousness from Clint and was about to walk toward the jet when he noticed Thor still standing there. He appeared to be in deep in thought as he glaze at the markings below him, as if trying to understand something.

"You alright there, Thor?" His voice seems to shake Thor out of his trance as he looked towards the Captain.

"Of course, Captain. It's just..." He trailed off as he returned his glaze to the markings. "For some reason, I've felt like I've seen these markings before. Especially that urn. It's like I'm suppose to know them, but I can't."

Steve nodded in understanding, "Well, if you can't remember them now, try to remember them when we get back to the tower. Maybe that way we could tell what they are and try to find out what those Ice Wolves are planning."

Thor nodded as he and Steve went toward the jet, not without taking one last glance at the markings behind his shoulder before continuing on his way. He hopes that he could remember where he had seen the markings and urn before, because it's leaving some sort of ache in his heart, one that he thought was locked away fro a while.

Unknown to the Avengers, that urn they were looking for was near the marking, covered in dirt as the top part of it was sticking out. It was small, like a goblet, and had the colors of frost blue and silver mixed together. Though it did looked kind of dirty since it was half-buried. The lid appeared to be opened slightly from one of the Ice Wolves dropping it.

Suddenly, a strange white liquid suddenly began to seep out of the urn. It began small at first, but as if by magic, the lid suddenly popped open and out came the strange liquid. It poor out of the urn quickly like running water as it began to fill in the snowflake markings, which seemed to be a lot because once the liquid covered the entire marking, it finally left the urn.

As if it was alive, the liquid began to rise up which soon began to take shape of something. The liquid suddenly began to look like as if some humanoid figure began to rise up, then something long came from the humanoid figure has it finally reaches it full height.

Once the transformation seemed complete, the liquid soon began to disperse and instead came in place of a young woman hiding underneath a large hooded cape made from brown feathers.

The woman hesitantly raise her head, as if she hadn't done it in a long time. Her light turquoise eyes hold curiosity, but caution and weariness as they slowly darted at her surroundings. She looked as though something was about to pop out at her. Whenever she thought she heard something like a twig snapping, the woman would snap her head at the direction she thought it came from, the light boldness of her red hair seemly snapping like a whip around her should every time she snaps her head.

Soon her glaze found the urn on the left, and the eyes that once hold the fearful expression now show intense anger and resentment. Though it make look harmless now, that urn was powerful, but it's powers didn't bother the woman. No, what bother her was the pain it caused her.

With great swift, she removed one of the brown leather gloves on her hand and stuck it out at the urn. Suddenly a magic white blast came from it and hit the urn, as soon as it made contact, the urn explode into tiny pieces. It was no more.

Even with the urn gone, the woman still hold that indescribable rage. It seemed that she was in a trancelike state as her hands shook uncontrollable, while appears to be sparking white light from her ungloved hand.

The sounds of a jet caught her attention as the woman looked at what was in front of her with her wide, unblinking eyes as she watches a jet rising into the air and began to fly away from where she was.

With the sudden urge to follow it, the woman began to trail after it, but not without leaving behind scorched footprints as she walks by.
