(This will be shit because I am lazy right now, I just want a basic story.)
Zixivino was a simple girl, raised to an adoring, beautiful mother, and a bloodthirsty drunkard father. Her father constantly beat her mother and threatened to kill her mother and Zixivino, saying that elves belonged in trees and not in a hole in the ground, where their town was located. Zixivino became antisocial, dark, and ignored people most of the time. She was lonely as a child.
As a teen she became prone to wearing dark colors and stopped wearing all but black altogether. Her mother eventually began to teach her how to be an artisan and allowed her to work with her mother. Her father became drunker and drunker, starting to beat his only son, Zixivino's younger brother, who their father would not allow to have a name. He was dark, moody, and brooding. He cared about nothing and no-one. One day, bandits raided the town and killed her no-named brother. Her mother mourned and her father didn't seem to notice.
Once Zixivino had grown up, she immedialty left. Begging her mother to come with her, but she refused. She said her heart belonged to this town and she loved it so. Zixivino knew something bad was about to happen, and it did. Only a week after she had left, she got news from a tavern owner that her entire birthtown was destroyed, no-one was left alive. In blind fury she raced back to her old home, finding ashes, and her mother's descrated corpse ontop of a pile of burnt bones in the middle of town. A pit was nearby, full of body-faced creepers, all hungry for flesh, Her father's was nowhere to be found in the small pile and that was the first time Zixivino felt a true, blinding, white-hot rage. She tracked her father further underground and farther than she had ever been, once she finally had a fresh trail, he dissapeared. Into the end.
Zixivino swore that whenever he came out, he would be killed like the pig he was. She carved her name into the walls near the portal and left. He would get the memo, the death he would soon endure.
