Kelpo's initial read had been wrong. It was not a tunnel at all.
The chamber was a natural formation; a vast vaulted ceiling of icicles and frozen rock.
Less natural was the crashed ship at its center; a twisted ruin of curling metal and burst organic matter. Frozen coolant had warped the ice around it an oily black. The rock itself had been scorched and frozen over. Whatever impact trajectory the ship had taken, it could not be described as a gentle landing.
There was no impact hole from the surface. This had sat here for hundreds, if not thousands of years.
Kelpo's scanner wand cheeped manically. He twisted it off, leaving the two men alone in stunned silence.
After a moment, Kelpo was the first to speak.
"So… what do you think it is?" he asked.
Telin's eyes never left the shattered ship.
"Opportunity."
