609 Under the Deep Sea

The Petrachelys descended silently and quickly into the water, leaving the storm behind. The footage from the external monitor was converted to several large holographic projections, which formed an immersive scene. It was as though the heavy armor around the bridge had disappeared, and they could directly experience the feeling of being in the deep sea.

The waves above them faded away and soon they could only see some light flickering from above, the endless lightning thunderstorm of Io illuminating the stars. The first new energy that the sirens of Io came into contact with in the "Air World" was lightning. But it was more than 1,000 years after Ewenna discovered the starry sky and the sirens experienced "sunlight" for the first time.

Unfortunately, these historical details had been submerged in the surging waves of Io. Maybe no one would ever know again.
