I think you misunderstood what I meant. couple posts ago I already talked about the Khuzeit/Khergit relations.
In Warband, we learn that the Khergit lands were conquered by an UNKNOWN EASTERN KINGDOM (Not Empire, Kingdom). This is a fact. There is nothing to argue about that. And actually we learn that it happened 50-100 years before the beginning of the Warband. (The character actualy says that his grandfather saw it. Thats why i said 50-100 years.) Which means, 100-150 years after Bannerlords beginning some Eastern Kingdom has to start invading the Khuzait or Ex-Khuzait lands, which ends with Khergits taking control and migrating to west and conquering the Eastern Calradian Empire. This is a fact. It is in the game. You should talk with the companians read their story if you want to learn about the lore.
No matter what others say, the game is highly influenced by the Turkic/Anatolian history. That's why Khergits have more background story than others. They are going to add a dlc about the eastern kingdom. Just like the timurids or mongols, it is going to invade Calradia. It doesn't matter if it is going to be a dlc or a stand alone game, i am pretty sure they want to do something like that.
By the way, it wouldn't shock me if they added something like ''Sultan Hakim's grandfather was actually a Khuzait.''
Like what I said, the game is influenced by the Turkic history and ''Mamluks'' are accepted as a part of it.
