On a different note, what kind of wars took place around this century.
I suppose Eisenkreis ([@Alfhedil]) fought one just a few dozen years ago at worst. His new borders are recent conquest.
Most likely they used tanks in that.

Eisenkreis has fought with Kzechverin for centuries, and it's highly likely the original cause for their Unification War was Kzechverin adventurers. The recent joining of Kzechverin and Eisenkreis is actually not related to the wars, but actually the union of house Desrosier and Kzechverin between Marianna Desrosier and Csilla Kzechverin. There have been tanks used in outside conflicts, however, namely skirmishes with royal houses in the Kzechverin territories, so it would definitely be a visible thing to the world of Eisenkreis' technological standing.
