The Aquatic Planet

Hao Ren led Lily as well as Vivian back to the Petrachelys, and as the frigate slowly descended into Io's orbit, Y'zaks asked about their findings in the derelict spaceship.

The siren queen immediately came forward to listen too.

"It's the Zalazarn. She couldn't escape and was destroyed in orbit." Hao Ren shook his head. "The starship's rear wing and the lower pipe intersection area had massive penetrating rents. They were about a few kilometers long. These were from cannon fire. We even found one of the duds inside the ship, and that bloody thing almost ruined my hairstyle."

"Cannon fire?" Y'zaks never considered such a possibility. "So the one that destroyed the siren's civilization wasn't the First Born or the brain monsters, but a... mortal race that uses cannon fire?"
