RTF is a global modification that replaces all towns in the game.

I picked up the word "невольник" in Battle Brothers; there, weak Barbarian units in poor armor were called "невольники."

I specifically avoided the word "раб" because, at least for me, that word evokes associations with Black people on cotton plantations, but this is hardcore slavery – industrial slavery. My "невольники" don't produce anything; they simply fell into dependence on stronger Orcs. Now they chop wood, cook food, and perform minor tasks... and maybe even watch over slaves of other races.

Of course, there might be a couple of cities in the Orcish faction with plantations, where "невольники" work like real slaves, but these are exceptions to the rule.

I think the Orcish slavery system has a certain religious undertone. In my idea, retraining is a kind of ritual that endows warriors with strength. So, it turns out that any "невольник" can become not just a free warrior, but even a shaman or a giant – quite a career climb.

Then the question arises: do all Orcs start as slaves? No, many wild Orcs start at T2 – as hunters. In any case, Orcish hunter tribes encounter and take prisoners. These prisoners become "невольники," and after earning trust, they become hunters again. But sometimes, these "невольники" are simply sold to a mountain city, where they receive an upgrade (armor) and are assigned to a combat unit. And then, again, it is possible to transition to archers... if a city experiences a food shortage due to overpopulation, some groups of Orcs will leave it and become new hunter tribes, and the whole process will repeat.
