"That's six!!"
With this, I have won the bet against Willhem. Out of the fifteen kirsurks that appeared, the soldiers took four down already. There is still one remaining and Willhem has managed to kill four of them with K'nor and the other soldiers' help. So, even if he kills the last one, I still win.
While hovering in the air, observing the situation, I see a pack of Longinus Dall leaving the fort. There are about ten of them. With their six legs and their long big tail, they do have that frightening look to them. The next moment though, the fire ball of a mortar falls on the pack and just like that, it is annihilated. They didn't even get the chance to do anything.
