What is needed to become a Turanian aristocrat?

First, be born a Turanian, not some scum from a conquered satrapy. Second, be born to an influential father who holds a position. Third, it must be the case that there are few sons, or you are one of the eldest (otherwise, the road leads to the guard, or straight into the expeditors or other riffraff). From there, you can obtain some rank within your father's estates or sphere of administrative influence and live off provincial taxes, or study further at an academy for nobles to supplement the basic upbringing you should have received at home (if you didn't—your father, grandfather, uncles, and brothers are all among those who pissed the country away, since no one bothered). There, you'll become an honorary humanities scholar and can stop shaking down the market for taxes and instead preside over courts, manage customs, and engage in other intelligent pursuits. If your father is a total goldmine and doesn't care much about what becomes of you, you can spend your days idling in the manor, drinking wine, and bedding concubines. Later, you inherit the fortune and the land, and people will even collect the taxes for you while you live high on the public purse, waking up only occasionally in a cold sweat when you dream that the Shahanshah has found out in detail where the money from your assigned post is going.

How is the slave trade organized in this country, and do slaves come from any region?

Slaves are found almost everywhere from everywhere, except for the Shogunate, where no one will ever sail, and they themselves only sail to the continent if life is miserable—or conversely, in search of a merry one; Ardor, where there are no slaves; and various nomads, for whom no one would bother transporting valuable cargo that is much easier to sell in Lashia, Turan, or Fenderin. And in Ormonde and Bardilar, the slaves are, of course, the most wretched.
The apparatus of coercion is mostly the same everywhere: there are coloni, serfs bound to the land who must work for themselves and the landlord. They can be sold and relocated (except in Ardor), but they are not considered slaves in the full sense; they have a right to property, albeit limited, and usually the state protects their lives to some extent because such a colonus is the foundation of the economy. Killing a colonus without cause or excessive oppression is, at minimum, bad tone (Divef, Rochery), and at maximum, a crime for which even a nobleman will be punished.
In all countries except Ardor, there are personal or family slaves who do whatever the master says. Among these, skills and quality are always valued; they can hold positions under a master ranging from toilet cleaner to tutor for his children. A slave belongs personally to the master, and the state doesn't give a damn about them. If the master wants, he kills; if he wants, he frees. A manumitted slave is not considered a fully free person, but in Turan, "fully free" people are a minority anyway, yet they manage. They are bought at separate markets and are treated as household conveniences; in the modest family of some guardsman, there will be a cook and a groom among the slaves; in a satrap's house, there is even a slave assigned just to hold the fan.
And finally, there are state laborers—slaves who own nothing and toil for infrastructure. A small number of them is pointless, and only a country that is very strong in military and administrative terms can afford to base its economy on slaves. Ronstrad lives entirely on its slaves; household ones are minimal, and there are no coloni at all. In Turan, there are many such slaves; they are attached to satraps just as armies are attached to satraps—they are a means of achieving state goals, recruited and managed personally by the governor. Such slaves slave away in mines and on construction sites. Most are prisoners of war and their descendants. Such slaves are never freed. How miserable their life will be depends on the individual satrap, but generally, it is always miserable; nothing is better than sleep. They sleep in barracks, wear what the masters aren't sorry to throw away, and eat just enough to have the strength to work... In Fenderin, there is also a layer of such slaves, and in Lashia, but there they are bought at markets, usually by high nobles or city governors who can extract profit from them.
By the way, there are also dark elves in the setting; a dark elf female can cost as much as a small Castle, as can a regular one, but a regular one is much harder to catch. Besides the fact that they hardly age, they do not crossbreed with humans.

What are the plans for the maps?

I'd like to perhaps create some way to steer the randomness into a more interesting channel for a specific player, but otherwise, it's pretty much as usual. Penalties with resets, unlocking a race/skill, starting bonuses, mental disorders, slaves, companions, as we like.

Is there printing?

No, everything is by hand. Literacy is an expensive pleasure.

What about languages (not ancient ones), what will the characters speak?

I'm probably not ready to build a grammar from scratch for you like Tolkien. Let's assume we speak a Turanian-Northern koine. Ardorians learned Northern, everyone in the south knows Turanian, Turan borders the North, trades, and somehow learned to communicate, and in general, almost all languages actually differ within a single family.
