Tunnels

Beneath the surface lies a vast network of chambers connected by a complex series of tunnels. Several of these were partially collapsed, and appeared not to be in use by the worms. We piloted the Rift Sphere into the quietest. The walls are covered in a web-like substance which keeps the shale and loose gravel in place. We speculate that these are secretions from the worms. Most of the chambers are empty, but some contain murky pools of water. Within one, we encountered a clutch of large, mineralized cocoons half-submerged in the liquid.

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

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

• Harvest the eggs.
  • Leads to event: Swallowed
• Proceed onward.
  • Leads to event: The Nursery

Stellaris events fire in chains — one event leads to the next. Here is how Tunnels (astral_rift.1810) connects.
