Maybe something like a supplementary background book "Great Wars of the Past Centuries - by Konrad Quedlinburg".
A book not focusing on specific factions, but on famous conflicts between them.
idea for taking the scenario book and making stories to go alongside each scenario.
It’s be nice for the world of T9A have its Austerlitz, Towton, Bosworth, etc ...
even the criticism of the book could be helpful!
