Sera walked behind Kelvin as they decided to abandon the corpse of the mantis shrimp behind for now.
The crater it had emerged from was deeper than it looked from ground level. What had appeared to be maybe a ten-foot hole actually descended much further, the walls smooth and deliberately carved rather than naturally formed. Kelvin's scanner was going haywire now, beeping constantly as they descended into darkness.
"This isn't natural excavation," Seraleth observed, running her good hand along the wall. Her injured shoulder throbbed with each movement, but the suit was doing its job. She could feel the nanomedicine working through her system, numbing pain, accelerating healing. Not fast enough to matter in immediate combat, but enough to keep her functional.
"Nope," Kelvin agreed, his prosthetic hand holding a light that illuminated their path. "Something dug this deliberately. Question is what and why."
