I like interconnected histories, so lemme ask you something. 

You mentioned that the Miesenfrylk fled past the Eisen river from the south, "at the behest of vast armies and legions spawned in the hellish lands in the south."

By coincidence, my nation will be based in southern deserts around that area and has a barbaric past, plus a large orc population. So would you mind if I mentioned that the orc armies previously pushed some of the humans to flee to the north?

The ones who fled could be your Eisen, and the ones who remained could be the humans who live in my nation.
