Underground World

The chosen three were gearing up to go down into the underground, with others helping them get suited up.

"The underground should be a vast area. If you don't locate the energy crystals, make sure you find a safe drilling spot," the professor advised the three who were about to head down.

Lyra stood still with her arms outstretched as the technicians fitted her gear, her eyes fixed on the pitch-black abyss below.

"The safety ropes are ready. You can begin the descent," someone announced. The three of them stood at the edge, tense and silent.

"I'll go first. You two follow me slowly and wait for my signal," Lyra instructed through her protective helmet, her voice slightly muffled.

She summoned a bright green light with her fingers. "Since communication devices might not work down there, we'll use my powers as the signal. Three flashes mean it's safe, two flashes mean pause, and one flash means we retreat immediately."
