On the dock, more than a dozen researchers in white radiation-proof suits were busy. They operated massive hoisting robotic arms to slowly lift specially-made torpedoes, each marked with a distinctive luring agent symbol on its casing, which stood out sharply in the dim light.
"Be careful! Don't damage the stabilizer!" A middle-aged man wearing goggles shouted harshly, his voice echoing within the enclosed port area.
The hydraulic system of the hoisting arm emitted a low hum, cables taut, as torpedoes were steadily delivered into the submarine's vertical launch bay. Another team was checking the vessel's seal integrity with detectors scanning back and forth over the welds, the beeping of the device sounding like some eerie counting.
On the submarine's conning tower, several members of the Holy City dressed in black uniforms were communicating with the internal compartments through intercom, their voices low but with an undeniable authority.
"Loading progress?"
