On the surface, the situation inside Muster Ground was becoming increasingly strange as a deep vibration suddenly spread through the ground beneath everyone's feet.
At first, the vibration was so faint that most soldiers believed they had imagined it.
But within a few seconds, it became stronger, causing the ground to tremble beneath their boots. It made many pieces of equipment shake where they had been placed.

The soldiers stopped their training one after another.
Those who had been practicing with thermal weapons lowered their rifles and looked around in confusion, while the soldiers sparring in the training grounds separated from each other and stared at the ground beneath them.
