So while I wait for the Undead to start scraping on the door, some developing details of the human kingdoms of my currently unnamed world.
The main armies are the three Northern Kingdoms.
All three have distinctive kit and style.
Kingdom OneKingdom one has extensive grass lands and so can field more cavalry than its neighbours.
The average soldier wears a long Brigandine coat and an almost conical helm.
Infantry tends toward spears or swords.


The other two kingdoms are the result of a schism between a single kingdom. This means that they do have some commonality in equipment (a shorter brigandine to their neighbours) but distinctive helmets.
Kingdom TwoKingdom two infantry sport a reinforced helm.

They tend to have a lot of archers.
Kingdom ThreeKingdom three has less archers, but their infantry sport a wider flatter helm that provides protection from arrows.

The soldiers tend to use spiked maces rather than swords.
Northern TribesNorth of these kingdoms there are various disparate groups, which occasionally band together and strike south.

Southern KingdomsSouth there are numerous kingdoms.
They have various types of infantry and archers.

They also have more warriors in heavy armour, and the warmer climes allow for more and heavier cavalry.
