How much of a hand could we have in shaping the culture and whatnot of these kingdoms?

For my prince, I was thinking of something like a border-kingdom at the eastern edge of the Imperium. A long history of fending off foreign invasions and dealing with influxes of nomads and immigrants.

Well, I have to [i]try[/i] to keep it into continuity, but given these nations are not as large as some of them become in the future there are a lot more of them in this timeline— so kingdom/house creation seems definitely plausible and for a kingdom to fending off orcs, goblins, monsters, gnolls, and cursed beasts is within the framework of the world. As weird as it sounds humanity is pretty unified right now, though things are slightly changing in that regard due to the fact the god who interacted with them has sort of gone silent. Some think Gaea has abandoned them, others think someone has taken her from them, and there are people who think they have betrayed her in some way. The people of the faith in the imperium are at loss because they have not been able to hear her for a few hundred years and things are starting to cause waves.
