Monster system:
Monsters are tracked by availability and population tiers (Breeding Pair-Rare-Uncommon-Populous). Each population tier is able to support fielding a certain amount of monsters in the army. If too many losses are suffered from war monsters the population tier will drop. Players may search for and attempt to hunt/capture/breed monsters with Major Actions, gaining population tiers.
Naval monsters function differently, each nation may have one unique naval monster.
Example:
Denmark:
Military:
Available Monsters:
Populous Wyrms (Can field wyrms equal to a tenth of manpower or 1,000, whichever is higher.)
Uncommon Hydras (Can field up to 500 hydras)
Rare Rocs (Can field 10 Rocs)
Breeding Pair of Dragons (Cannot field dragons as part of armies. However, one or two heroes may ride them.)
Current Nation Monster Pops:
Germany:
Rare Dragons (Reasoning here is that Germany doesn't seem to have placed much focus on dragons, hunting them more for prestige for select nobles.)
France:
Uncommon Dragons
England:
