"Great!" Alli responded positively. She reflected Ayumi's optimistic attitude in her own pleasant smile. She sat back and placed her left hand on her hip. The fingers of her right hand continued to twirl the scalpel. "Well, then. I think you might know where I am going with all of this." As she spoke, Alli looked down at the scalpel in her hand indifferently.
"You must feel that incredible surge of energy in your body still. Because my supply of Aether is so vast and focused, I can feel it more or less like that all the time. You would, too, if you learned to control your Aether to an extent beyond your so-called "natural" limits. Feels different, huh?" She smirked playfully. "As I said before, Aether exists in all living beings. Even I can not fully explain it, so people like me often use a simple word devised by humans to describe it: magic. Your own Aether exists in your body, seeping out and surrounding it. The Aether of other people and creatures also exists within them, leaking out." She gestured off with her left hand to demonstrate the Aether escaping from the body. Her emerald eyes seemed distant as she gazed about, thinking of ways to explain this mysterious, pervading force, before she fixed her sight back on the little girl.
"You can train yourself and hone your Aether, much like you can hone your body in martial arts. Some think of it as a sort of spiritual or magical training. Starting out, this kind of regimen is very, very difficult and complicated. Fortunately for us, your body accepted my Aether. My Aether will work with yours now, as well as give it a good boost. This will allow you to perform some amazing tasks... including healing." She knew Ayumi came here for this, and Alli had become just as excited to finally get this girl ready to heal. With only a little more explanation out of the way, Ayumi would be ready.
"My Aether is also naturally and inseparably attuned to healing, among other things. You will find it easier to use it in this task. Think of it like a training period. With my Aether, you can probably start mending wounds right now with little difficulty. But, eventually you'll use the supply I gave you up. By that time, you will need to learn how to work with Aether, how to precisely control it, strictly manipulate it, gradually build it, and painstakingly focus it. That way, you can begin to cultivate the Aether within your own body. Your own Aether will work better with you than even mine will. In this way, you may become a healer." Alli had once again assumed a very serious expression and grave tone. Even as she felt optimistic that Ayumi could become a great healer, she also presented a challenge to Alli. Learning to control one's Aether did not come easily. Sure, Alli could continue supplying Ayumi with her own Aether while they remained in the same vicinity. However, if Ayumi never learned to control her own Aether, she would never grow as a healer.
"Now, we begin your training!" Suddenly, Alli flipped the scalpel in her right hand to hold it in a strong grip. She slid her left hand out in front of her on the table, placing it in between her and Ayumi with her palm planted on the table. Her right arm snapped down and in an instant, Alli had driven the scalpel into her left hand. She slashed down, creating a deep, gaping wound on the back of her left hand. She kept her eyes locked onto Ayumi's the entire time, and she did not even flinch when she drove the blade into the back of her hand. She showed no sign of pain as if her entire left arm had gone numb long ago. Blood began to seep out out of the fresh cut. In fact, Alli had to suppress her body's naturally accelerated recovery process. Normally, a minor laceration like that would heal on the spot in the same manner that Alli had healed the man's bullet wound earlier.
She removed the scalpel from the cut, letting loose droplets of blood drip back into the wound. She then placed a scalpel on top of the cabinet from which she retrieved it. Now came the first test.
"Ayumi, place your palm right over mine. The closer the better. I hope you do not mind blood, but you will only see more of it if you plan on being a healer." She did not sound really apologetic, but she did not feel that way, either. If Ayumi could not handle the sight or feel of blood, she would not make a very good healer. "You should feel that energy inside of you bubbling up. Focus it. Draw it inwards and concentrate. Think about its nature and familiarize yourself with it. Then, channel it through your arm and towards the palm of your hand. The palm is one of the easiest places from which you can expel your Aether. Do just that. Think about the Aether, and will it to help me, to heal me. Contact my body, and the Aether inside of it, and transfer your benevolent spirit into my hand to heal me."
As ridiculous as it sounded, it could work. Very few ever succeeded on the first try, but Alli would not tell Ayumi that. If Ayumi did succeed, she would prove to be a prodigy not often witnessed. Alli figured she would have to explain a little more about how Aether worked for Ayumi to understand it, and--for that matter--believe in it. In essence, the Aether filling Ayumi's body would recognize Alli's Aether, communicate with it as the link to her body, and induce cell's to grow, regenerate, form, and even exist. Her Aether could actually feed the victim's body with the right building blocks of life to reform the tissue and repair the damage. Such was the nature of the ethereal, esoteric force most often referred to simply as "magic," but which Alli and her fellow Guardians knew as Aether. To master Aether meant ascending the limits of the average body and typical existence; to even become a deity.
As Ayumi tried, Alli fondly recalled her own first attempt at healing. She had received the initial lesson a tad differently. For one, her instructor had forcefully and unceremoniously injured Alli at the time, pretty severely, and demaned that she heal herself to live. As hard as she tried, she could not save her own life that day, and so began her hellish practice in the art of healing under her spartan Magister, or instructor. Fortunately for Ayumi, Alli injured herself instead of her pupil to get things started.
