Yawning Chasm
The "Yawning Chasm" event in Stellaris — flavor, choices, and how to trigger it with the event console command.
Yawning Chasm

Utilizing an air quality sensor, we searched for the highest localized concentrations of the toxic gas across the lush lands. Beyond a patch of berry-laden shrubberies, we were led to the mouth of a vast crevasse in the center of a clearing. Waves of the thick, pink miasma emanated from it in irregular intervals. We believe that the gas is being produced by a subterranean creature somewhere at the base of this fissure. Finding it, preferably alive, could provide unique research opportunities.
