Lisandro nods. If there is to be secrecy, as few people in the room as possible. 

“Classes first. How would you explain what classes are and how they work, to a young child who had not yet learned anything else about them?”

"Okay, so, my main theory here is that the translation miracle is just... not working right... so interrupt me if you suddenly realize what I'm referring to." She takes a moment to recollect the explanation she gave her youngest. "When you're eighteen years old," that was a bad start, from the top, "on someone's eighteenth birthday, they can enlist in an army. At that point their class will be 'Tradesman.' Your commander can promote you to a different class, but at first they'll only be able to choose between Tradesman and Soldier. As a Soldier you won't be able to work a trade, but you will be able to equip your first weapon, which will be a shortspear. You'll train as a soldier until you qualify for a different class--likely a Fighter or an Amazon, but if you have high stats to begin with you might be able to jump right into Ninja, or, more rarely, Wizard. You shouldn't worry too much about what classes you do or don't qualify for from the start, because it doesn't make a huge difference in the long run, it won't take very many levels in the grand scheme of things before you qualify for whatever class you'll be leveling as--well, these days, I think they like to promote you back and forth between different classes every few levels, for better-rounded stat growth, but they didn't do that when I was a girl... when you're level 99, you can ask your commander to promote you to a different class whenever you want, if you qualify for it, which at that point is just about changing your alignment around. Most of us spend most of our time as Tradesmen, since Tradesmen earn Goth and the other classes only spend it... um, what else, oh, I guess I should list the classes that people have? Unless you're born with a unique class or gain a hidden one, typical classes you'll see are, uh, for women it's Tradesmen, who do trades, Sirens, who do Advanced Magic, Priests, who do Healing Magic Plus, Freyas, who use spears and armor and do Advanced Weapon Magic, Dragon Masters, who buff dragons, that one's pretty straightforward, oh, they use rapiers, and Dianas who use bows. For men, it's Tradesmen, uh, Sword Masters, who are pretty much what they sound like, Paladins, who use swords and shields and armor and Basic Weapon Magic, Cataphracts, who are heavily armored and use spears, Enchanters, who use dolls and buff golems, Beast Masters, who use whips and buff beasts, and Ninja Masters, who use claws or can use Advanced Magic, but they can't use spellbooks, they just automatically use whichever element their enemies are weak to, it's a mixed bag... is any of this clicking?"

“I don’t think this is translation error. That is not how it works where I come from at all. We don’t all have to join the army to get magic and power, I was never a soldier but I still faced danger and increased in circle. We also let people in the army practice trades, though maybe some places still separate the two.”

Most of the specific powers and abilities are confusing, but that’s to be expected from outsiders. Which means this probably is another plane. This is offensive to his sensibilities. He knows that in Cheliax they sort you into wizard track or cleric track or conscript, and that in Osirion they go all in on separating things by man and woman, but places that aren’t tyrannies do it more sensibly. 

At this she seems utterly aghast. "If you don't join the army, no one can promote you when you qualify for a better class!"

“I don’t need someone else to, I have always been a wizard since my childhood and just get better at being a wizard.”

He floats up in the air and does a flip, then continues the conversation while hovering.

"You can level to the cap in Wizard, certainly there's nothing to stop you, but why would you when you could promote to Archmage and level as one of those instead??"

(Oh, she forgot to mention Archmages with the other male classes. Well, she knew she was probably missing one, that's just life.)

The witch cuts in with, "He might have a unique class, or his people could be demihumans which can't promote. You should be slower to make assumptions."

You guide considers that, and then says, "Right, I think I should talk to my aunt and have her promote me to a leadership class. I'll come back straightaway and form a new unit you can join. Then we'll know whether or not you could change class."

This must be a translation error. Though Felandriel joining the army is an amusing thought. 

“If I were to join your unit and then wanted to leave, how would that go?”

Gonna take more than an offer of information or new abilities, to integrate him into whatever chain of command system this is.

"Well, I'm going to disband the unit once we've tested this, since I do have a dayjob and Tradesman isn't a leadership class. If you want to leave before then... you could ask?"

The witch decides that your guide isn't thinking of all the things which could go wrong and decides to list a few. "She could take your things and leave you with your class's base equipment."

"I could already take his things, I'm level 99 and he isn't, I doubt he could stop me."

"She could change your class against your will, and if you don't qualify for your current one anymore you wouldn't be able to change back. Or she could promote you into an undead class like Lich, and you'd be stuck that way forever."

"If I knew where to find a Ring of the Dead, I wouldn't waste it promoting someone I hardly know into a Lich!"

To the witch. “You. You get it.”

”I will not be joining any units at this time”

Your guide rolls her eyes dramatically. 

"If you like I'll promote as a Priest so you're assured of my Law.[1]"

1. This language has a word for Lawful, and has a word for Chaotic Evil, and has a word for Neutral. Those are the alignments, according to this language.

"It would take all of several minutes for her to flip her alignment," warns the witch. "In this age, people have the alignments they want, or that they need for promotions, but rarely the alignments they've earned."

Good on them, hacking whatever simple little alignment system they ended up with. 

“I don’t trust just by alignment anyway. I will, if you permit, stay in this city for however long it takes to learn more about this place. If I decide you’re trustworthy enough to be worth giving that power, it will probably take a long time.”
