The mere thought of a new tribe of demons joining the battlefield immediately made Alistair and the rest who overheard Reign's words turn serious.
Even without that, the current situation they were in was dire enough. A new kind of enemy, one that was very well versed in being stealthy and staying out of sight was a big threat to anybody.
Even if it was the demons they had previously fought, the change in strategy would make the following battles much more difficult.
Reign simply continued looking ahead with a nonchalant smile on his face. The enemy was still far away, so they couldn't hear what they were saying, but they could see them, and Reign didn't want to alert them.
"No matter what it is, we have to keep calm, everybody gets ready for battle, but don't make it obvious, I don't want the enemy to realize we have noticed them." Reign said calmly as he continued staring ahead with a calm and peaceful expression.
