To Thau, the best offense is a good defense. Their abundance of stonecutters, blacksmiths, and armourers ply their trade in fortifications when the need arises. Thaun soldiers are clad in heavy mail, armed with hefty weapons, and trained to be the anvil on which their foe's hammers break.
When a Thaun encampment is in danger of being overrun and captured, fuses are lit and the site abandoned. Kegs of canandust reduce defenses to rubble, ideally taking the enemy with it.
