The Nautilus surged upwards, its engines roaring against the pull of the deep. Kai's hands were steady at the controls, his mind racing with the weight of the evidence stored in his suit's data drive. The surface world needed to know the truth about the underwater city, and he was the bearer of that revelation.

As they ascended, the crew prepared for the worst. They knew the city would not let them go easily, that their guardians would pursue them to the ends of the earth to keep their secrets safe. But the crew of the Nautilus had something the city did not—determination fueled by righteousness.
