Night Raid (3)
As the night wore on, the heroes and natives on guard duty became more relaxed. As far as they saw things, there was no way that they would be ambushed after the battle in the city. The only danger came from any natural fauna, and they were confident of spotting their approach from some distance. Their attitude was so relaxed that they did something that nobody on watch duty should ever do. They sat around their fires and looked directly into them!
Witnessing this act, Shadow grinned at their stupidity. 'Idiots, they've just made themselves night blind.' Since they were staring directly at a light source in a dark environment, it would take time for their vision to adjust to the low light levels when they looked away from the fire. This was the perfect opportunity for the Tu'Thrag to begin their assault.
