A week has passed since Erica first woke up in the Zellas hospital. The day after the exercise with the charges, she was deemed fit to leave the hospital, as much as it seemed to baffle the doctor who cleared her. Her, Damon, and a couple of Altean Army mechans traveled for four days nearly non-stop to reach their destination, courtesy of the mechans driving and not needing sleep. The trip was done in an armoured car built to transport five, painted the same beige as the mechans. It was largely silent when driving, just the hum of motors and maiga harnesses providing some background noise as the car jostled along. Erica had never been in such a vehicle, and at one point needed to have the car stop so she could expunge the breakfast she had earlier. She avoided getting anything on her new clothes, consisting of a blue long sleeved V-neck shirt like the ones she liked from home, black combat pants, and combat boots reminiscent of those that came with her guard uniform, all courtesy of donations made to the Altean Army when requested. The right sleeve of her shirt was pinned in place to avoid having too much material flopping about as she moved. Damon had a new longcoat as well, though it was identical to the previous one, minus the hole Erica had put in the last one.
The trip was grand in scale, with them starting at Zellas, west of Copperwood, then heading south to reach Dy'As Ridge, the massive mountain range that formed the intersection of four of the world's five continents, making a rough cross running north-south, east-west. They were on the northern continent, Bladefell, however their destination was on western Flamehaven. In order to reach the other continent, they had to take The Throughways, a series of tunnels that went through the mountains, and bridges that crossed the diagonally running channels of water that cut through the Ridge, called Crehss' Cross. Running The Throughways took most of a day taking one of the middle-lengths tunnels, as that was the closest to where they'd started and would spit them out on track for headquarters. After the final two days of travel traversing Flamehaven a bit north of the equatorial heat, they made it to headquarters.
Erica didn't even recognize they were at a base initially, as it was camouflaged to blend in with the tall granite plateau it was built into. A disguised gate opened, breaking the illusion, and they rolled into an underground complex hidden from sight. Erica was somewhat nervous about entering such an enclosed space, but figured that if she were in any danger with Damon and his mechans, she would have never woken up in the hospital. They drove through a lit tunnel until they reached the garage. From there, Erica was given a rudimentary tour of the facility. She was shown her room, which was sparsely furnished with a very basic bed and simple dresser. She requested a vanity to be added, and one had since been brought in. The common room, kitchen, laundry, and conference rooms were all given quick explanations. There was not much in the way of entertainment, so Erica made do in her downtime reading the rather dry selection of books in the common room or fiddling with the dice and playing cards on a table there. The kitchen was mostly just a stove, a nearly empty refrigerator, and cabinets stuffed with non-perishable rations. Some basic pots, pans, and utensils, enough to prepare the slightly more involved rations and little else, were also stored there.
Erica wasn't in any of those rooms at the moment. Instead, she was in the base's gymnasium, practicing throwing bolts of maiga at Damon, who had graduated her from charging while they were still driving, saying they had to make the most of their time. Erica's arm was strained from hurling bolt after bolt at Damon, who either grounded the attacks or caught and dissipated them. She had practiced a little with using other elements, briefly flinging flame, water, and earth at her mentor before settling back into lightning. For whatever reason, the bolts felt right. The other elements, while she could see uses for them, didn't fit her as well, as though they were tools with ill fitting grips. So, for the time being, she was using what she felt most comfortable with. She had just conjured two bolts at once in an attempt to surprise Damon, but he caught them both, mashed them together, and planted the resulting maiga ball into the ground.
"I commend your creativity," he said, standing back to his full height, "but stick to the exercise, if you would."
"Oh, come on!" Erica exclaimed, "Does nothing surprise you?"
"After witnessing as much combat as I have, it takes some rather novel ideas to surprise me. Throwing twice the number of projectiles at me is nothing I haven't seen before."
Erica was about to ask what he had seen, but decided she shouldn't ask questions she didn't want the answer to.
"Those bolts," Damon continued, "I understand you tend to shape through your hand. Tell me, have you tried using both?"
Erica's mood instantly soured. "In case you forgot, a certain omnicidal monster took it upon himself to make me an arm lighter, so I can't exactly use both."
"I remember. Try to use your missing arm anyway."
"How can I use something I don't have?"
"In this case, with some practice. Remember the first exercise I had you do in the hospital? Do that again, but use your right hand. Picture your arm, the maiga flowing through it, both your body's and what you're channeling. See the arm the body remembers, and wield it."
"This is stupid..." Erica, exasperated, dropped her left hand and looked to where a raised right would be. She halfheartedly attempted to feel energy in the missing body part, only to find she could actually feel something. A tingling along her arm was felt, even though it wasn't there. Blinking a couple of times, she put her full focus into it, and began to see the maiga in the room more clearly. Among the floating motes of dull light, she saw lines of energy where her raised arm ought to have been, complete with an open hand, palm to the ceiling. Experimentally, she flipped the hand in her mind, the mental command replicated with the maiga ghost. She attempted more movements with the phantom arm, all successfully replicating the motions her arm would have made. Holding her palm in front of her again, she now attempted to focus maiga into the space just above her ghost palm, and the energy obeyed. Before she knew it, she had a melon-sized ball of power floating in front of her. She grasped it and started waving it around, astounded by the ease with which she could do this. It was as if she'd never lost the arm, merely had it become nearly invisible. She allowed the ball of maiga to dissipate into the background of the room.
"Believe me now?" Damon said, having watched with arms crossed the whole time.
Erica felt sheepish. "Yeah... sorry, I should have been more open to that idea..."
"You've got it now. Now, we continue where we left off, this time using your right arm only."
Erica agreed, and the two of them played their deadly game of catch for a couple of hours before Damon nodded in approval.
"You've picked up on shaping in general fairly quickly, but this was even faster than I'd hoped for. You're well on your way to being able to handle a prosthetic limb."
Erica perked up. "A replacement arm?"
"Ha, what else? It will be powered, of course. By you and your shaping."
"Wait, I'll need to feed it myself?"
"Constantly. It shouldn't be too demanding most of the time, it should be like using the original arm in terms of mental strain. As for shaping, you have such a tendency toward higher amounts of maiga flowing around, you shouldn't have a problem outside of trying to overcharge the limb."
"Overcharge?"
"Getting more strength or speed out of it, though I'm getting a little ahead of myself. Let's get some water, then I'll show you something in the workshop."
Erica's curiosity and anticipation spiked. The workshop had been off-limits to her before, with an explanation of "it's hazardous" to keep her out. She wasn't so bull-headed as to go barging in when told not to, especially since Damon had emphasized that she wasn't to go in there. While he was a bit blunt and lacking tact, he knew what he was doing, and was her boss. Perhaps he wanted the arm to be a surprise? That seemed a silly reason to keep her out of the workshop, but it was a possibility.
The two of them went to the kitchen to get a drink of water, then they went down the hallway. They passed the laundry, the common room, and the conference room before walking the granite halls for a bit until they reached a door labeled "Workshop". When Damon opened the door and stepped in, Erica was a little disappointed to see that the door hadn't been locked. She could have just gone in? At any time?
She followed him inside. The workshop was a large room with uncountable tools, ranging from the smallest wrench to an industrial lathe. There was a smithy, many workbenches, and harsh overhead lights. There was so much here, she had to look around briefly to see Damon's darker silhouette strutting toward one of the further workbenches. After catching up, she saw that there was a towel covering a long lump on the bench.
"Didn't have a tarp or something for that?" Erica joked.
Damon shrugged. If he understood that that was meant to be at least light-hearted, he didn't show it. "It matters more what's under it than what I used as a cover."
"Never mind. When did you have time to work on this? We've only been here a few days, and you've spent most of that time training me..."
"It's important we get you back to full functionality, so this project became top priority. Any time I could spend in here working on this I took."
Erica wasn't sure how to feel about this. She became flustered. "Did you sleep?"
"No."
"What?!" Erica wheeled on him. "What do you mean, 'no'?!"
Damon raised an eyebrow, clearly confused. "I mean I worked on this rather than waste time lying down? I don't require the same things a regular body does. Sleep is often wasted time when I could either direct the Army or pursue Diezens."
"Sleep is rest and recovery for your body from the day! If you've been as busy as you say, you should be dead on your feet now!"
He shrugged. "I'm fine, as you can see."
She couldn't argue against that. He seemed as rested and aware as when she met him. "You said you don't need the same things a regular person does. What do you mean by that?"
"Like you and your shaping, I have my own quirks. However, that's not what I brought you here for; I brought you here to unveil this...!" He said as he pulled the towel back with the least flourish Erica had ever seen someone muster for a big reveal.
That could be forgiven for the effort that had clearly been put into the prosthetic arm that lay on the bench before her. It was made of slightly blueish metal, with a narrow, downright skeletal upper arm with a ball socket on the side mimicking the original arm's bone structure. The elbow was a black metal encased stone servo leading to a much more bulked out forearm. The forearm was somewhat squared, with armour plating on the top and sides, in a darker blue metal than the majority of the arm. The hand looked both durable and very realistic in its shape and proportions, each digit built to an exacting standard.
"This... this is for me?" Erica asked, unsure.
"For none other."
"It's... different," Erica mused, looking over the bone-thin upper arm compared to the slightly bulked out forearm. The hand somehow looked familiar. She couldn't shake that idea as she looked at it more closely. "Aren't prosthetics usually trying to mimic the original limb a little more closely than this?"
"Due to the altanite I used in its construction, I needed to reduce weight where I could. The upper arm is still plenty durable, even without the bulk or armour of the forearm," Damon explained.
"The what in its construction now?"
"Altanite is a metal we have exclusive access to in some mines north-west of here. We've staked a claim to the entire region altanite can be found in, so we don't have to worry about it falling into the hands of the nations of the world, or worse, the Diezens."
"What makes it so special that you need to hoard it?"
"The metal is incredibly dense and heat resistant, making it excellent for defensive use or to make mechans. However, that comes at the cost of vastly increased weight compared to steel. So, most often we use it in an alloy, to get some of the benefits of the altanite without making it prohibitively heavy."
"So it's some kind of super metal that you just happened to find and be able to use without anyone else having access to it? What about battlefield salvage?"
Damon shrugged, "Altanite requires immense heat to work, more than most blast furnaces are capable of. We also take pains to recover as much as possible from our own casualties. I've seen the occasional altanite-alloy thing make it to market from opportunistic smiths, but it's largely a non-issue."
Erica shook her head in disbelief. The hand of the prosthetic was still bothering her.
"It should be a perfect fit," Damon continued, "I replicated the measurements of the original limb as closely as possible."
Erica stood still, dumbfounded for a moment. She turned to face Damon, and plotted out her next words with lethal precision. "The measurements... of the original limb."
"Yes?"
"The original limb, that was severed."
"... Yes?"
"You meticulously measured, my fucking severed arm?!" Erica shouted, now truly in disbelief.
Damon, sensing something was amiss, looked between the prosthetic and the bewildered woman in front of him. "How else was I going to be able to make a new one to your specifications?"
"Oh, I don't know, ask me?! You could have measured my left arm! It's close enough! Please tell me you didn't do anything else creepy with that arm..."
"I had it cremated after it looked like you were to survive, otherwise I would have returned it to you for burial."
"Ah, I see. Just destroy some of me before I even wake up, that's great!"
Damon was thoroughly confused. "Did... you want it for something?"
"No! It's just weird what you did! You don't just go around, manhandling severed limbs, even if it's to get measurements for a replacement! Would you do that if I still had my arm on me?"
"No? Because then you wouldn't need a replacement?"
"Oh, gods... How are you this smart, but this dumb?"
"I don't follow."
"I see that... permission is important when it comes to touching someone, severed limb or no. Got it? Handling the arm to dispose of it, fine. Getting all close and personal with it to get measurements I did not clear you to take? Major violation of personal space."
"Oh? I've never had this complaint before. Though, I guess I haven't had to do something like this before either..."
Erica gave an agitated sigh. "Well, it's done now. Thank you for the arm, I can see that a lot of work went into it. Don't go measuring me without my say-so again, okay?"
Damon nodded, a perplexed expression plastered over his face. "There's an altanite-alloy coated stone socket that needs to be surgically attached before the arm can be installed. When do you think you'd be ready for the procedure? There's a nearby village who's doctor I trust who can help me with it, so we'd be able to go get it done fairly quickly after your approval."
Surgically attached? "Whatever, let's get it done ASAP."
"Right. It's getting late, so we'll go early tomorrow. You are dismissed."
As Erica turned to leave, she wondered how she ever got caught up in all this.
Oh, right. The gods spun their celestial pickaxe and decided she was the best candidate for whatever plans they had.
