Just as their jubilation started to peak, a monotonous voice cut through the air, dampening their spirits.
"It appears many have survived this onslaught, but do not rejoice too soon. This was merely the first wave of beasts. You now have thirty minutes to rest and regain your strength. Prepare yourselves, for the second wave will be fiercer - more powerful, greater in number, and even more ferocious," the voice intoned ominously.
The sudden announcement cast a shadow over the crowd's elation.
Someone let out a heavy sigh, voicing the collective worry that hung in the air. "How many more waves of these fierce beasts must we endure?" he pondered aloud.
