Stratospheric Vents Studied
The "Stratospheric Vents Studied" event in Stellaris — flavor, choices, and how to trigger it with the event console command.
Stratospheric Vents Studied

We have determined that the vents on … have formed over millions of years as superheated gas and sediments cool down and solidify. The remaining fumes in the lower thermosphere form clouds that the Tiyanki feed on, plowing through with unexpected grace. This affords us a rare opportunity not only to observe the creatures in close proximity, but also increase the colony's appeal to extraplanetary visitors. Alternatively, the vents could be harnessed for exotic gas refining at the expense of driving away the fauna from their ancient feeding grounds.
