So the final (?) list of armies/races/peoples for fantasy KPS will look like this:

Royal humans (this also doubles as the general human list for historical games)

City folk

Dwarfs

Martial elves

Small folk

Horde orcs

Ratters

Brute orcs

Gnolls

Barbarians

Devout 

Dark elves

Undead

Lizardfolk

Wood elves

Gnomes

That should be enough to cover most ranges of figures I can think of, and the ones that arent covered can be fit into one of the above. I may add one or two more but I am not sure.
