Some time later, your radio tells you to clear the area. As you're watching, an aircraft, really just a streak of silver in the sunlight, catches your eye. It drops down, flies low over the town then lifts upwards as the hive tower erupts in flames from the ground up. Chemical fire races up the structure, and consumes it from the inside out until it bursts like flaming paper. Dark shapes writhe in the inferno but fall still and are consumed.
The incendiary bombs also start fires in the area. Though there are no buildings close by, material on the ground catches and burns hotly, if briefly.
Just like that, it's over. The aircraft turns around, flies back toward Castle Refuge, waggling it's silver wings as it flies overhead of Echo. And is gone.
You stay and watch for a time. The surviving insects, devoid of their queen, simply join her in the flaming pyre. One by one they file in, workers, soldiers, hunters. When the flames begin to subside, you are fairly certain that every last one is dead.
A drive through town shows the devastation, the south side of town slowly burning down as the northerly winds spread embers that way. The remainder of the town seems unlikely to ever house people again, stripped as it was for accessible timber.
Still, people are resilient. Some newcomers may find the dead town and its ghosts of being eaten alive by an insect army to be better than sleeping in the woods.
