Carlos lounged comfortably on one of the mayor's fancy sofas. At 23 years old with a healthy body he really didn't need cushioned upholstery, but he liked how it felt. Honestly, he was probably more comfortable with high quality furniture than someone of his relatively low-income background should be in this world. Spoiled by the mass production factories of modern Earth, I suppose. All of this stuff here is probably handmade. Er, make that definitely handmade. Unless they have magic factories I haven't heard about, or something. He mentally shrugged. There was no point trying to change his attitudes toward furniture now. While this world might have higher prices for a lot of things than he was used to, he was also a lot richer than he was used to thanks to having become a noble lord. People would expect him to treat fine furniture as cheap because of his station.

I might have the physical habits of a couch potato, but at least I don't look like one. Too skinny. Not as skinny as Amber, though. He smiled as he watched the young woman next to him on the sofa continue animatedly expounding on their recent adventures together. She was lanky, with few curves to speak of and spindly limbs, far from any conventional picture of feminine beauty. Her hair, a slightly lighter shade of brown than his own, was cropped short. He thought she was 18 or 19 years old, but wasn't sure. Have I really never asked her age before? ... Would that be a rude question here? Regardless of her age, she had grown her confidence a lot since their first meeting a few weeks ago. She'd found her footing in a new life that she'd seized with utter determination, and he saw no sign of the shyness that she'd first greeted him with. The way her potential was finally blooming was beautiful to watch.

Carlos turned his gaze to the sofa across from them and carefully held back from laughing at the expressions Trinlen was making as Amber wrapped up explaining the events and developments they'd gone through since their introduction to him at the Royal Mage Academy. Carlos had contributed a fair amount to the explanation at first, but Amber had taken to it with enthusiasm when she arrived, and he could tell she was enjoying it. The young man in front of them, newly graduated from said academy, was on the edge of his seat and leaning forward, hanging attentively on every word. His casual attire, plain and made of cheap materials, looked thoroughly out of place on the finely embroidered velvet of the sofa, but he'd shown no sign of even noticing the finery around him. Excitement warred for control of his face with surprise, disbelief, envy, and dismay.

Amber finished her impromptu monologue, and Trinlen slowly schooled his face into a neutral expression. His voice was tense and tightly controlled. "So... In short, you're telling me that in the mere two weeks since you met me, you discovered a mana-poaching conspiracy of nobles, were abducted right under the noses of two royal guards without them even noticing, absorbed mana so fast that you gained 6 levels in a day and a half - so unfair, by the way - somehow learned an obscure portal spell from just its name and description, found evidence of a conspiracy against the Crown, and personally met a princess." He paused, then threw his hands up as he wailed in frustration and disappointment. "And I missed it!?"

Carlos threw back his head and burst out laughing. He couldn't help it. Trinlen just sounded so much like a little kid who'd barely missed out on a candy store giving away its entire stock for free. It was such an incredible light-hearted contrast with how everyone else viewed these same events that the sheer ridiculousness of it was overwhelming. Amber joined the laughter a moment later, shaking her head in amused disbelief, and after a few more seconds Trinlen started chuckling too.

Carlos's laughter eventually trailed off, and he took a deep breath to settle down. "Thanks, Trinlen. It's been a very stressful two weeks, and laughing like that helped release a lot of it. Feels good. Anyway, what have you been up to? I thought you would take a whole month to graduate?"

"Technically I only said 'next month', not that it would be at the same point in the month. But yes, this is earlier than I expected. The normal graduation ceremony is still a week and a half away." Trinlen shrugged. "They didn't explain the reasons, but after what you said I'm guessing your meeting with the princess prompted her to do something. The vice headmaster called me to his office yesterday morning, a few teachers grilled me on my classwork, and they declared I'd passed my exams. Then they told me to pack because I'd be teleported to my new employers the next day, and here I am." He sighed. "Hmph. Now I won't get to humiliate Norla in front of the whole academy when she gives her speech." Then he perked up and grinned widely. "But it sounds like you two are going to be so much fun that I'll get over it in no time!"

"I'm not sure if I agree with your idea of fun, Trinlen, but if it motivates you to help us more then that's good enough for me." Carlos chuckled again. "Anyway, do you need some time to get settled in? You might need to think about lesson plans for us too. We don't need just catalogues of incantations to learn anymore, at least not for simple ones, but I believe you learned other things in the academy too. You mentioned creating your own spells, as I recall."

Trinlen nodded. "I did mention that, yes. I'm guessing your lack of need for a catalogue is because of your newfound ability to somehow pull entire incantations from thin air? You'll have to at least tell me about the limitations of that so I'll know what I still need to teach you, but yeah, there are other things. For one thing, there's your sloppy terminology! Why does no one outside of the academy care about properly distinguishing between the states of mana? Is it really that hard to understand that calling aether, mana, and essence all by the same term obscures your meaning and often causes confusion? Or are people so stupid that they can't even understand the difference?"

If you stumble upon this tale on Amazon, it's taken without the author's consent. Report it.

Carlos blinked and exchanged a look with Amber. His comprehension aid informed him about the distinction the instant Trinlen spoke the terms. That would have been nice to know earlier. The comprehension aid is a house secret, so we should let him explain. "At least for us, it's just ignorance. I don't think I've even heard the other two terms you mentioned, and certainly no one ever explained them. So, what is the difference?"

Trinlen paused, cocked his head for a moment, and slowly deflated after his impassioned rant. "Yeah, okay, that's fair. I don't think I ever heard about it before going to the academy either." He sat up straight. "Aether is what you've been calling ambient mana. It's thin like air, and it's everywhere. Its only use is converting it to mana or essence. Mana, using the term with proper precision, is thicker but still fluid like water. It exists primarily in people or creatures and is used as fuel to supply power for spells and magical effects. Essence is hard and solid. It is the material that soul structures are made of, as well as the forms of active spells and enchantments. Am I clear so far?"

Amber answered first. "Yes, I'm familiar with each of the forms you described. I have questions about more details - so many questions - but you should get properly settled in, and maybe eat lunch, before we really get down to it. Have you spoken with Mayor Stelras yet? Do you have lodging sorted out?"

"I went by his office first. He's having someone take my luggage to an inn. The Adventurer's Haven, I think? He said something about a 'low-value target' and having an empty suite already booked." Trinlen's eyes widened. "Waaait a minute. Is he putting me in the room you two were abducted from?"

Carlos shrugged. "Sounds like it."

"Nice! Think there'll be any evidence left of how it was done?"

"Haha! Probably not by this point, but you're welcome to look. Now go get unpacked, eat a meal, and start planning your lessons for us. I'm glad you're here, but we have some other things to do too."

Trinlen nodded and stood up. "Sure. I'll be back before you miss me."

Carlos waved as Trinlen sauntered out the door. He and Amber sat in companionable silence for a while as he felt the mana - or essence? - of Trinlen's soul moving off into the distance. "Well. That was interesting. It's good to have him, but I was expecting a bit more time to think and plan before he'd get here."

"Yeah." Amber stretched and then leaned back into the sofa's cushions, luxuriating in their soft firmness. "So, how much are we going to tell him? How useful will his knowledge even be for us, now that we have, what did you call it, the reference documentation? That bit about the states of mana is good to know, but is it really relevant and important, and how much more can there be that's not in the documentation?"

"Be careful talking about that out loud, remember?" Carlos relaxed and draped his arms across the sofa's back as he focused his mind on their mental bond through Purple, their friendly dungeon core. [On Earth, we made many languages similar to the language of incantations, and we had the reference documentation for all of them. We even published that documentation free for everyone to have. Teachers for those languages were still useful, and even critically important for many people. Having access to knowledge doesn't mean you automatically understand how to properly apply it. There may be related knowledge we have no idea even exists. There could be techniques and patterns for how to use the language that are simply outside the scope of the documentation. Perhaps most importantly, a teacher can use their experience to notice a student's mistakes and correct them before they become problems.]

[Hmm.] Amber bit her lip, thinking. [Like how I knew about making soul structures and synergies between them, but had no idea about the importance of being able to examine and fix them, I suppose.]

Carlos nodded. [Yeah. And that's a really simple example. I know some that are a lot more complex, though I'm not sure how many of them are even applicable for incantations. Inversion of control, dependency injection, factory patterns...] He shook his head. [Just the context knowledge needed to be able to fully understand those could take days or weeks to teach well enough for you to use them. I could maybe explain the basic ideas faster with some simplified analogies, but that would lose so many details that I doubt it would still be useful.]

Amber paused. [... Even my comprehension aid is baffled by the terms you just said. It translated the individual words that you said, but all I got for the phrases is a confusing jumble.] She chuckled. [Anyway, I concede the point. Trinlen will still be able to teach us important and useful things. We still need to decide what secrets to share with him.]

[A lot depends on how good he is at keeping secrets. We don't actually know him all that well yet. He's certainly fun, and he seems clever, but for assessing his integrity we're leaning pretty hard on just a janitor vouching for him.] Carlos frowned in thought. [In order for him to do his job, he needs to know that we can only "pull an entire incantation from thin air" if it's a simple one. He does not need to know the full details of `help`, however, and most certainly does not need to learn to use it himself. That secret is a very sensitive one, where even just letting too much knowledge of it spread would lose us a major advantage.]

[Definitely. No casting `help` where he can hear it, and don't say anything about it that's not directly relevant for his teaching, either. Not until he's earned our full trust.] Amber lapsed into silent consideration. [We should introduce him to Purple. We'll kind of have to at some point anyway, and the really valuable thing there is Purple himself, not just the knowledge of his existence.]

Carlos nodded. [True. I think that probably is the least sensitive of our house secrets, and being able to call him through a bond with Purple would be useful.] He chuckled. [And maybe his cleverness will end up producing some good ideas for Purple to use. See if he can find a more productive outlet than pranks for his creativity. And then... If he keeps that secret well enough for long enough, we can consider trusting him with more secrets.]

Amber sent back wordless agreement.

Carlos started sitting up, lifting himself out of the comfortable cushions. "Well, we should get some food ourselves, too. And maybe introduce Trinlen to everyone else along with Purple." He stood up and spotted a letter he'd set aside when Trinlen arrived. "Oh yeah, and what do you think we should do about Kindar?"

"Wait, what's this about Kindar?"
