the cavern

Within the cavern, the air was thick and wet, many different colored molds and fungi clung to the walls, some glowing giving the chamber an eerie feel. There was no entrance or exit, just the empty space beneath the planet's crust, alone in the gloom. A shadow twitched in the corner. It twitched once again and expanded, like a black balloon on the verge of its limits. A loud pop sounded along with a bright flash. Four figures flew out from the shadowy flare to land hard on the cavern floor.
