+unit_description="The guardians of the capital city of Weldyn, the Wall Guards patrol the walls of the city, shooting at approaching enemies with their crossbows before their opponent can retaliate even with a ranged attack. Because they are mounted on high walls, they cannot move anywhere except on walls and the roofs of castles."
