The fall of Repest has begun.
The fall didn't just start now. It started hours before even the monster tide appeared near the town. Yeah, the first step of the fall was that the town didn't get the warning regarding the monster tide's move up in the invasion timeline.
The scouts failed to report back to the town. This made it easy for the monsters to catch the defenders with their pants down. Though once they were in the eye line from the top of the walls, and the town was alerted, it was already late enough for the monsters to take advantage of the situation.
The few readily available defenders made themselves into a makeshift defence to stop the monsters until the others joined them, but they couldn't hold on much. The first line of defence broke down easily, killing many of the defenders and injuring many more.
