Darius didn't take much longer to enter. He then moved to the driver's seat and started up the sub slowly, making sure everything was a-okay. He smiled when he saw that the sub had a full fuel tank, but the max distance it could go was unfortunately 500 km.
While this was not enough for him to cross the long-distance home, he could use it to reach the nearby Napari Island to find shelter for the time being.
Darius detached the sub from under the yacht and switched its headlights on so he could see in the darkness of the water. It was nighttime, so visibility underwater was poor.
Darius maneuvered the sub around using its controls, raising the propeller speed to the maximum in the direction of the island. Since the sub came with a remote GPS and area sensor, he could continue to move despite the darkness.
