Chemically Cleansed

This planet's atmosphere contains a staggering amount of antibacterial agents. Sensors indicate zero signs of organic life in the immediate vicinity. Even on a microscopic level, it has been chemically removed. There is a faint biological reading emanating from a distant cavern, but from this range it is impossible to qualify. Several clusters of robots have been witnessed patrolling the skies. They have not yet reacted to our presence.

The command below will trigger the "Chemically Cleansed" event in Stellaris:

When this event fires, you can choose between these 2 options:

• Investigate the robots.
  • Leads to event: Drone Encounter
• Explore the cave.
  • Leads to event: Signs of Life

Stellaris events fire in chains — one event leads to the next. Here is how Chemically Cleansed (astral_rift.2600) connects.
