When an opposing army brings in the big weapons, your kingdom has no choice but to ante up or fold - and a trained Battle Mage from the Guild of Arcane Combatants if nothing if not a big weapon. But what happens your generals and their generals have a common goal?
A military organization, the Stalkers are a hunting/mining militia that are known for wearing full body shrouds that easily hide them in snow and other slushy terrain. The lightly armored warriors are known for the speed, stealth, and the vicious wounds inflicted by their hunting hatchets. Many of the Stalkers keep crop-eared warhounds with them, both for hunting, companionship, and in war.
