Name: Castiel but is often called Cassie by those who were close to her.

Age: 18

Race: Half Human-Half Lunairan

Bio: Castiel was born to a rather wealthy family and had a great young life. It was when she turned seven that things took a turn for the worst. Her father had worked for the government, creating robots that could fight enemies. These robots did well at first, fought in wars for the country so that none of their men had to. It made her father, and in turn her family, well known and even wealthier than before. But, because of his well liked status, when the aliens first become known to the public, her father was one of the first people to be attacked, as well as her mother. She was hidden away in a secret room of the house until the aliens had left when they were finished murdering her parents. It was the next day that her uncle, an old military buff, found her and stayed there with her, making sure she survived. 

That year was the year everything went downhill for the humans. The robots her father had made for the government were soon of no use, as after just a few attacks of those robots, the aliens were able to learn their weaknesses and destroy the robots quickly. The aliens, on order to avoid loosing many of of their own they instead of killing the remaining humans directly, had a sickness spread throughout the planet and left temporarily on their ship, letting the disease take over and do their dirty work for them.

For years, her uncle kept them safe and hidden, and somehow he managed to not catch the disease for a long while. He would go out and gather supplies for them. For a long time he was doing well. But, it was when she was 14, that Cassie began to notice her uncle weakening. He was growing older, and thus had a more weaker immune system. Then, one day, after going out for supplies, her uncle came crawling back into their secret hide away, dying from sickness. Within the next few days, he suffered greatly. He realized the suffering would only grow and the disease would take much longer for him to die. He asked Cassie to shoot him and though she refused at first, she knew it was best for him and so, the fourteen year old innocent girl was forced to kill the last human she would ever be close to.

For the next few years, Cassie had somehow managed to keep herself alive since her uncle's death, and thanks to her being able to move fast and the fact she can out smart the remaining humans and savage animals, she has kept out of deaths grip. And now, ten years after the aliens came and with all other humans besides herself dead and gone, the aliens are returning.
