Chapter 47: The Minefield
Sarah took slow, hesitant steps over to her enchanting table, removing the glass dome. The fist-sized construct of gold and crystal lay there, innocuous. It didn't glow. It didn't radiate energy. It didn't shimmer or distort the air in any spectrum I could perceive. And yet, there it was. If it worked, it was by far the most valuable object in the home. A completely unique expression of the soul of its maker, potentially a revolutionary addition to the combined knowledge of the world of Enchanters. Potentially a revolutionary addition to the lives of all of us in the room, and hundreds of thousands of others with Thaumic dependencies across the world.
I gently laid the still-napping Nibbles down on the couch before stepping over. There was a hush among us. The nerves were strong. We knew what came next. I cleared my throat. "Sarah, it looks like some congratulations are in order."
She shook her head, staring at the Greater Masterwork, not wanting to touch it. "Not yet. We need to test it. Until it is put through its paces and codified, my requirement is not satisfied."
I turned to my wife, who was looking precisely as nervous as I was feeling. "Love, it's on you right now. Are you ready to test this? I wouldn't blame you if you want to wait, it's been a big day..."
Lucy shook her head. "No. We need to do this now. You were the one with the big day today, I can do this. I... don't want to lose my nerve. I don't want to cost both Sarah and our daughter their chance at this."
"Who am I to say no, then? Sarah, the floor is yours. It is time to test this."
Sarah paused for a moment. Took several deep breaths. "Okay. Okay, this is it, huh? Lucy, Jay, you two can stay. Everyone else, I need you to not be in the room for this part. Need to reduce the variables, and the free-flow Hunger can screw up my initial data." Nobody much liked that, no matter how necessary we all thought it was. Especially Emily.
"What will you do if something goes wrong?"
I was the one to answer. "Emily, you'll be within three seconds of getting to us if that happens. If that isn't fast enough, then you being in the room wouldn't have helped. Sarah, is there anything she can prepare for in case it's needed?"
Sarah thought for a moment. "Concussive force, thermal and thaumic burns. Those are the big risks right now, other than the whole thing just collapsing in on itself."
"So... the things I keep in my aid bag for you anyway. Specifically. Good to know I'm on the right track."
Sarah looked at the fox. "I didn't even realize you did that."
Emily looked right back, levelly. "And that is why I do."
In short order, the three of us were ready to start. Nibbles was still on the couch, though now awake enough to perk up his four ears and look on with interest. Sarah had given the device a thorough examination, and found nothing obviously wrong. "Okay. Lucy. How much Hunger do you have in the tank right now?"
"Just ticked down to 72%."
Sarah jotted some notes down. "Alright, this first test is going to be to check its function and efficiency when running on Hunger energies. Like a battery, basically. What I want you to do is just like one of my Gold Batteries. Reach out to it and drop 20% of your Hunger pool into storage, then pull it back out after a two or three second pause. I will be standing across the room in order to sever the free flow between us."
Sarah walked as far from Lucy as it was possible to be. I could see that the flow wasn't COMPLETELY severed, but it was very slow. I nodded. Lucy, in her turn, got a look of focus on her face as she reached out towards the device. All of us had used Sarah's Silver and Gold Batteries countless times. They were integral to more than one aspect of our teamwork, letting us utilize what would otherwise be wasted mana generation. This would hopefully be no different, and as I watched I could see Lucy's shimmering Aura flow outward into it. The Greater Masterwork began to shimmer softly in my sight, my unique abilities letting me suddenly perceive the Hunger energies stored there.
A moment later, Lucy reached back out to it, this time pulling her power back from it. The Aura around the battery ceased to be, and Lucy's regained its former power. "I'm at... 68%, Sarah."
My legs went weak, landing me on the couch. The tension went out of Sarah, too, I could hear her relief. Whatever else happened, she had managed a truly unique thing. The first functional Hunger Battery in the world. By itself, not enough to be her Greater Masterwork. Others had done similar things in other domains. Heck, she'd called some of them up for advice along the way. Still, this was her accomplishment.
She had a calculator out. "Okay. It looks like approximately 90% efficiency per transfer. Looks like 80% on the surface, but you transferred twice. That's a lot better than I feared it would be. The Hunger Box the government issues out to feed underage Succubi is only 20% efficient." Sarah closed her eyes for a moment, getting her own thoughts in order. I could see how they wanted to race into theory, could practically hear them going in every direction, but Sarah was a professional. She knew what needed doing, and what she needed for her notes. "Jay, could you see Aura around the battery while it was holding Lucy's Hunger?"
I nodded. "Yeah. Looked just like anyone else's."
She looked concerned. "I wasn't expecting that, and it puts a lot of my other ideas about what you do back on the drawing board, but okay. Did it look particularly full?"
"Um. Really didn't. Well under half, if it's anything like yours."
Sarah stepped forward to let her Aura sync up with Lucy's again. I could see them balancing out. "Got it. Lucy, this next part is going to take some trust. When I step away, I need you to drop 45% of your maximum Hunger pool into the device. This will let me get some idea of capacity. Once you do, I will check its readouts."
Lucy nodded, and obeyed. Once again, her Hunger flowed into the device, this time reducing her Aura by much more than before. I was looking this time, and could see the previously-innocuous dots of material joining together what used to be Gold Coins start to light up... the pair between the first and second. Out of seven. I didn't make this thing, but if that meant what I thought it meant...
Sarah's eyes went very, very wide. Her breathing sped. I didn't blame her. If what I saw was any indication, that meant that the low end of this thing's capacity was right around 150% of Lucy's maximum. That went beyond crazy. The price tag on the materials alone was well into the low six digits, and that would be considered cheap for the capability that represented. I saw her look down at her notes. "I... I didn't expect that calculation to be accurate. Okay, okay, that means... Lucy, pull your Hunger back from it. Next up is Jay." As my wife pulled her power back into herself, Sarah looked at me. "You saw what Lucy just did. For the first test, I need you to push 5% of your maximum pool into this. If the estimates I made are correct, that should be safe. Still around half of its max. Lucy, come to this side of the room. This is the big hurdle, but this is where the most things can go wrong."
Sarah was many things. Reassuring was not one of them. They retreated to as far as the room would allow, and I could see Lucy mentally preparing to do something, likely casting Shield. Also not precisely reassuring on a personal level, but I was glad she was being safe. I turned to the battery, reaching out with my mind in the same way I did the mana batteries we used so often. I could feel it, waiting. It took a moment for me to calm my own nerves. So much could still go wrong, here, but I could do no less than my best. Deliberately, I felt the reserves within myself, and pushed 5% of my maximum to where it needed to go. The battery was again shimmering with Aura.
This time, the first three connectors lit up as my power obeyed. The device worked. I had, for the first time, managed to push Hunger energies outward. That inviolable rule that stated I could not be Fed upon had just been violated. Sarah had found a way to circumvent it. She nodded. "Okay. Jay, pull your Hunger back. You might be one percent short from before, depending on the specifics of things, but you might not."
I did so, finding that I was in fact one percent lower. I again breathed deeply. Half of me was nervous about the Hunger we were burning in the inefficiency from transfer to transfer. The other half could remember that we were not in the state from two months ago. Every precious point wasn't going to make the difference between us living or going feral. She was looking at me expectantly. "It is done, I am in fact down by one point. Still got plenty in the tank, though."
Sarah nodded. Jotted down more notes than I thought my statement could easily account for. I saw her hand shake. I saw her grip her pencil tightly to steady the hand. "Okay. This should be the last true test. If this goes as expected, the Greater Masterwork is confirmed. Jay, I need you to push one single percent of your Hunger pool into the battery. Lucy, this time, you will be the one to withdraw it. We are sticking to small doses for safety until everything is mapped."
My part of the process was simple. I took a piece of myself and placed it for safekeeping in the Battery. A gift for my wife. She stepped forward, reaching out, and pulled the power I had placed there to herself. I saw the flow of it, the spark, as it came to her call. I saw the ripple in her Aura as, for the first time, she took in Hunger from her husband. She felt it, filled herself with it, taking the purest distillation of my essence into her with joy.
I saw the moment the look of rapturous bliss left her face, to be replaced with pain. My world slowed to a crawl as I saw her Aura roil as though struck with a bullet, as reality warped with her very physical mystical might. As Nibbles dashed from his seat to intercept the sudden lash of her uncontrolled power flying at me, as she began to scream in agony.
We were suddenly swarmed by the rest of our Guild. Emily and Amber were first, helped by the mighty Whitney. They were yelling something rapidly to each other, something about Magical Resonance Shock. In the far corner, Sarah was wailing a single word, over and over. "No!"
I felt like my limbs were made of lead as Gloria took Nibbles to apply what first aid she could. I found my voice. "What did I just do?"
Emily frantically yelled back. "Resonance shock! Whatever you just put into Lucy is the same kind of magic source she normally exists on, it burned her out! We have to get rid of it, fast. Amber, get the green vials out of my kit. The ones I won't give you copies of. Now!"
I could still do one thing. "Sarah! Sarah, your new ability! You just picked up Siphon, USE IT!" I put every ounce of forceful command I possibly could into what I yelled. Leaned into it in a way I never had given a command to one of my own.
