Here is an overview of the game, via its Steam page:
As the fighting rages in the Hundred Years’ War, you are the head of a noble family seeking glory in this tactical turn-based strategy game. Fight enemy factions and battle an evil force that has corrupted the highest echelons of power and is exploiting the conflict for its own gain through a violent and mysterious cult.
From your castle—your seat of operations—recruit, equip and train your soldiers to fight your enemies and protect the population. Build your squads to suit your needs as you set out to find the source of the Evil and thwart the malevolent plot.
Your management and diplomacy skills will be put to the test. Upgrade your castle, forge ties with other families, and manage your resources wisely.
With the world on the brink of collapse, there can only be one solution: Evil must be defeated.
