On the lake beside the capital, half of John's fleet was still battling the Frogman's pirate fleet while the other half continued bombarding Dritzuut's wall.
Nogg led players from Everlasting Heavenly Legends and their merfolk companions as they traveled underwater. Those players had Underwater Propeller Magic Scrolls, so they had no problem keeping up with the merfolk.
Nogg activated a skill that emitted an aura that caused all aquatic monsters below his level and grade to move away from his vicinity. This allowed his company of merfolk and players to move unhindered.
The water vibration carried the sound of explosions happening above the water. They also saw occasional flashes from above which were also caused by those explosions. John's fleet was firing blindly into the fog so most of the shots missed and hit the water instead.
