I use my dominion to sense the molecular structure around me. Oxygen is already present in the atmosphere, i can just collect it. Hydrogen on the other hand has to be separated from the molecules of water around by means of electrolysis. All I have to do is funnel the hydrogen and oxygen in a 2:1 ratio to create a pretty and steady flame, the spark can come from a small electric arc, easy.
However, it feels ... wrong and boring.
Why? Why does it feel like my instincts are complaining to me? What are they trying to tell me? ... Let's go along with them. First, what do I want? Create fire? Fire is just a rapid process of oxidation, there's nothing interesting at all on fire. I want something else ... I want to see the world scream, to distort time and space. I don't want just fire, I want heat, heat so powerful nothing can stand in it's way. All I can think of is ... the heat equation: u_t=α·Δu and the concept of diffusion. The heat equation just tells that heat will flow from hotter bodies to adjacent colder bodies, in proportion to the difference of temperature and of the thermal conductivity of the material between them, nothing complicated, just the same old fatalistic second law of thermodynamics that predicts that at the end of time all temperature will even out and nothing will exists but this.
... Wait a second, that is not an immutable truth anymore, I can freaking alter the thermal conductivity of air to focus the diffusion of an explosion in a straight line, and I don't need a medium to create heat, I just can steal it from the ambient reversing the direction of the equation and going against entropy. Let's give it a try.
The air began to tremble as heat was stolen from the atmosphere leaving a death chill around Aurora that caused her parents to panic. "What's happening?!" yelled Gladys while hugging her newborn child. Sid just opens his eyes in complete disbelief feeling the heat of his body leave rapidly. The strange phenomena only lasts a couple of seconds and then abruptly the direction changes, the heat accumulated was released and a scorching wave amplified by the previous cold assaults Sid's face.
Aurora altered the path of the heath diffusion to avoid her, and Gladys by extension, damping the effect of the heat backlash, so Sid was the only one feeling it's complete effect. It wasn't anything he couldn't tolerate with his magic trained body that even allowed to survive for prolonged periods of time in temperatures close to the boiling point of water. But it left a profound impression in him, specially the sparkling turquoise eyes of her daughter, the eyes of a small child that discovered a new toy.
In the list of ancestors of the Lionhearth family there have been genius (or monsters depending who you ask) that could naturally use magic, especially fire magic. However the effect usually was relatively mild and in all cases it manifested as the power to affect the fire already burning at their surroundings. This phenomena of absorbing and releasing heat was completely unheard of, not only as a instinctual use of magic, but not even in the systematic magic he had studied for many years. Generating fire and Ice were the two methods to produce heat and coldness respectively, there is no way to produce them directly. What is heat anyway? Is it possible to teach someone whose power he cannot comprehend?
Aurora finally was the one to break the awkward silence, raising her little hands with her fists closed as a sign of triumph and making the atmosphere vibrate slightly by rapidly concentrating and diffusing the heat around just enough to be felt unambiguously, telling everyone that was not a fluke.
She is be able to talk, ... well, sort of, is not exactly her voice but she can make the air vibrate to transmit any sound. However ,why should she do that? She found distasteful the idea of being forced to give explanations to inferior creatures when they learned she could communicate with them, maybe in the future when it becomes necessary or convenient, but not now.
"Ok, that was interesting and all, but I'm hungry", Aurora thinks, and immediately afterward she started groping Gladys breast while making small sucking sounds. She doesn't need a reaction from these people to feel validated and doesn't feel like waiting anymore.
Gladys woke out from her stupor and kindly says to Said, "I'm sorry Sid, but could you wait outside while I feed Aurora, she is hungry". Sid: "I'm not sure if it is a good to idea to leave you alone with ... her". Was he about to refer to her daughter as "that"?
"Don't be silly Sid, I will be fine, she is my daughter and I'm her mother, she will not harm me" responded Gladys.
"Maybe not consciously, but I think it would be wise to put on her an absorption mithril amulet to damp her powers for the time being"
"Then we will we waiting for it. Also please call Bertha and Rita to come over to help me, I think is better to have only the most royal servants around Aurora to avoid strange rumors." says Gladys, politely urging Sid to leave her room.
"I will come back with the amulet in about an hour. And also ... I will bring Luis to meet his little sister. Excuse me.", with those words Sid left the room, having completely forgotten to hold her daughter in his arms as per originally planned.
After the door closed, Gladys exposed her white breast and put her cherry nipple near Aurora's mouth. On the back of her head she found it weird that her breasts were not a little saggy, her nipples looked a lighter shade of pink, there were no longer any stretch marks on her belly from when Luis was born and even the few moles on her skin disappeared. However this details were wiped off her mind after the little display of power from Aurora. All she can think right now is about the curricula of magic she is going to teach her, starting as soon as possible.
