Everyone at the seaport walls was worried when Gold told them a hovering castle dropped a massive amount of rats to Wecha. As many of the soldiers were veteran survivors, they knew how terrifying the Rat Horde could be.
Thus, when the first wave of rats reached towards the defences of the seaport, renamed Port Bulwark as a sign of appreciation for the Northern Army's contribution, the defenders were befuddled by the number of rats running towards them.
The numbers were underwhelmingly less than expected.
Nevertheless, trained with the very same weapons used by Wecha's Militia, the Northern Bulwark Soldiers started to fire at the rats without discrimination. The small number of rats had also allowed the soldiers to adjust their formation further since it was the first live firing 'exercise' in which they used these weapons.
