Heart Fire redo on chapter one: Descent

This is a redo on my fan fiction with my OC Kaiya. I didn't like the original first chapter!
Heart Fire
Chapter one: Descent

As the sun peeked over the horizon, the town began to lazily stir. A small trickle of people headed in one direction, shivering from the cool morning mist. From her shabby bedroom a girl stirred, pulling golden strands of hair back from her face so she could watch the sunlight drift in through her window. Around her blueprints and gears jostled for space with strange machines that ran silently on well oiled parts. One in particular was chirping loudly at the sleepy youth. She reached out a slender hand and tapped it's bronze top. The incessant chirping stopped and all was silent. After a few moments another golden haired youth peeked in through the open doorway. She was small with gray eyes and a teddy bear clutched to her chest. The older of the two smiled at her and patted the bed next to her in an invitation to sit. The smaller obliged and snuggled next to her older sister. They shared a moment together, enjoying the company until a shout from downstairs called them into action. The older sister, she looked about thirteen, leaped off the bed and dashed to her dresser, pulling an assortment of clothes out and pulling them on clumsily. As she was tying up her long hair, her sister entered again, dressed in a small white dress.
“Kaiya,” she giggled, “you put your shirt on inside out!” Kaiya glanced down noticing the inside of her shirt facing out.
“Whoops! What would I do without you Liz?” She replied.
“You would wear inside-out shirts everyday.” She joked. “If not for me your wardrobe would be a mess!” Liz lightly danced out of reach from Kaiya before she could act in retaliation. Kaiya pretended not to notice and walked past her into the smoky hallway. When she arrived in the messy kitchen an unusual sight greeted her.
“Mom, are you COOKING!” Kaiya looked stunned. Her mother turned and laughed at the ridiculous expression on her daughter's face. She was pretty with dark brown hair and startlingly blue eyes. She could have passed as a rich woman if she wasn't wearing such shabby clothes. Oil stains were frequent and burn spots almost more so. A wrench peeked out from her baggy pants pockets.
“Trying to!” she replied indicating the burnt sausage in front of her. Liz emerged from upstairs, looking past Kaiya towards the food. She bolted on a direct path for it, leaping over a chair in the process. Picking up one of the burnt links, she dangled it over mouth already imagining the warmth in her belly. Quicker than Liz thought possible, her mother snatched it up and looked sternly at her youngest daughter. In reply the little glared back fiercely rivaling the stare of her mother. Kaiya's laughter interupted the death stares. They looked at her.
“I swear Liz, if looks could kill we would all be dead! You can eat once you get a plate.” Liz nodded and silently grabbed a plate, beginning to eat in a somewhat more civilized manner.
Kaiya's mother stared in amazement. “How do you do it! I tell her to do something and she glares at me. You tell her and she acts like a little obedient angel.” Her mother exclaimed, exasperated.
Kaiya smiled mischievously. “It's a sister thing.” Then she sat down next to her sister and grabbed some food. Her mother stared at the two looking, if possible, even more confused then before. They looked up at her, the picture of innocence painted on their faces.
“Why do I always get the feeling you are going to blow up the world some day when you look at me like that?” She muttered stalking back into her workshop. When Kaiya finished eating she grabbed a battered pickaxe from the wall, running her hands over the well worn handle, thinking of the hands that once held the same wood. Liz silently watched, abandoning her food. Kaiya snapped out of her thoughts and smiled at her sister in a reassuring manner.
“Off to work!” Kaiya tried to say cheerfully, the effect was ruined by her voice cracking. A tear rolled down her sister's cheek.
“I don't want you to vanish in the mines like dad did.” Kaiya clenched her fists. They sat silently for a moment lost in painful memories. Explosions, people running in confusion, a cart rolling by on squeaky wheels, a familiar hand falling out of the white blanket. Kaiya walked over to her sister and hugged her, letting the tears fall onto her shoulder.
“I wont. I promise. I can't leave you here alone.” Liz hugged Kaiya back tightly never wanting to let go. Kaiya gently removed her arms from around her waist and walked towards the front door. Her sister stared after her.
“Never leave me alone Kaiya,” she said, “ I'll have nothing left to live for.” Kaiya chocked back a sob and closed the door behind her.
“I will come back Liz. I will never leave you alone,” she promised to herself as she merged with the stream of people headed towards the dark depths of the mines. Kaiya clutched the wooden handle of the pickaxe, wondering if the promise held any meaning if she had no control of whether she came back alive or not.
