The scene in front of me was something I could not understand. How could the {Portals} still be open when the girls had already passed through them? This was an inherent limitation of {Portal}. While you could open an entrance and an exit, the path itself disappeared after the caster passed.
The Sirens, however, somehow got around this limitation, allowing six fallen zones to converge on this area. The scene was similar to the enlistment. We were a small group of people gathered for the coming stampede of the undead.
The ground shook as hundreds of bodies stamped towards us. Their snarling and grunting gave an idea of how hungry these fuckers were. Though I had killed thousands of these zombies, this was perhaps the largest number I had ever seen.
