Noticed

Unfortunately, we have drawn the attention of the creature. Head tilted to the side, an arrangement of scaled spines lifted outward from its neck. With quick, rhythmic pulses, the shimmering beast sent audible sounds in our direction. We'll be unable to study it any further. We predict it would be quite vulnerable if exposed to intense flame, as most of the other life around here tends to be. However, it may be best to escape now and cut our losses.

The command below will trigger the "Noticed" event in Stellaris:

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

• Escape.
  • Leads to event: Escape
• Burn the Creature.
  • Leads to event: Infinity Root

Stellaris events fire in chains — one event leads to the next. Here is how Noticed (astral_rift.1435) connects.
