The Host

Chapter One. Searching for Aefriol's Prison/A New Start

A hooded figure with a robe that was black in color was walking down the caverns outside the city of Blakewood, Missouri as the figure was looking for something in particular that was located inside the caverns. She was determined to find it and didn't care if it was trespassing or not, she had to find it.

The item that she was looking for was a crystal. This very crystal had the essence of her master Aefriol who had been imprisoned in ever since he had been banished from her home world of Mylithos, a planet a couple of galaxies away from the Planet Earth. Being a part of the Cult of Aethriol, the woman was exiled from Mylithos as well. From there, after finding the crystal, she would release Aefriol into this world after she found him a suitable host. Then Aefriol would take over this planet and eventually this entire universe.

"It has to be around here somewhere." the woman stated, "I am sure the council of Mylithos hid my master's prison somewhere deep inside."

She continued walking further into the caverns until she eventually stumbled across a crystal that was lying on the ground. The crystal was black in color, cloudy nonetheless. The woman smiled in satisfaction. She slowly picked it up.

"At last!" the woman exclaimed, "the essence of Aethriol! I finally found it!"

The woman took off her hood revealing her dark red hair, shiny blue eyes with intelligence in them, middle aged face and pointed ears, "He was exiled from Mylithos and so am I. I shall free Aethriol once I find a suitable host for my master, and once I do, this entire world, and eventually this universe will be under his mercy!"

"Lila, are you ready?"

Lila Barton looked up as she appeared to be annoyed, "Yes, Mom."

"Well, hurry up. The Fall festival is going to start really soon."

"Alright." Lila replied before speaking to herself, "Not that I agreed to going to this Fall festival, but whatever."

Along with her mother and her brothers, they moved to a bigger city in Missouri not too long after the death of their father Clint Barton, who was known as Hawkeye. Along with that, the kids moved to a new school as well. Lila did enjoy the new school as everyone was nice, but things weren't quite the same since her father died and she felt so withdrawn socially. The rest of her family was coping as well, but in different ways.

Her mother Laura Barton still had pictures of her husband as did Lila herself. Laura insisted that her children did not follow that same dangerous path her husband did as she did not want to lose any of her children in a similar way that she lost her husband, and apparently their grandmother Edith felt the same way as she had lost her son as well. On the other hand, Laura was deeply grateful that her family friend Natasha Romanoff, known as Black Widow, was keeping her word to check on her every so often as she did for the past month. Her older brother Cooper Barton was enjoying the social life in his new school as much as he possibly could at school, from attending parties and dances that his mother would allow him to attend to. As for her younger brother Nathaniel Barton, he remained attached to his mother, fearing that he would lose her too despite the fact that Laura assured him that she would be with him in this world as long as God would let her.

Lila met up with her mother and brothers and they headed to Kenwood High School where the Fall Festival was located. Not every student was in a costume, but some students were.

"See?" Lila told her family, "I told you not everyone would be in a costume."

"I know." Laura replied, "but you know your brother, he wants to do everything with his friends."

Lila looked to see Cooper dressed as Captain America while Nathaniel was dressed as Woody from the Toy Story movies as the family was entering in the school to sign up for the Fall Festival.

"It is a big school!" Laura told her daughter, "So do not wander off too far, okay? Also, Natasha will be here soon!"

The Barton family was unaware that not only was the exiled alien outside the school but that there would be an extraordinary adventure that would be coming their way really soon, closer than what they would think.

Author's Note: I decided to re upload this old story after finally finding it on A03. I'm going to see if I can find the last chapter(s) of this story as I know it was complete when I originally posted here but it wasn't complete on A03 for some reason. If not, I'll have to rewrite the ending and see what I can remember from it by memory.
