You know you will not be able to hold the fortress much longer. Its ancient walls crumble a little more with every massive claw that strikes them, and the beasts keep coming. Surveying the treeline, you spot movement to the North, East and North East, but nothing to the West. The Foregate, Left Bastion and Western Wall should be safe, however, you can hear the loud rattling of old equipment in the tunnel once again.

As you look to the East, you see a large shape snaking its way between the trees. A centipede-like monstrosity tramples over the roiling swarm of creatures, stabbing them with its spear-like legs as it thunders toward the fortress. It will cost precious lives to take that thing down unless you do something.
