Endless Rock

A vast plane of loose rock and gravel stretches before us. Above it hangs a pale, empty sky. No planets or stars can be seen here. This does not appear to be part of a galaxy or any known system. As far as our sensors can detect, this landscape continues infinitely in all directions. The surface is pockmarked with holes as large as some asteroids. All across the horizon, dozens of massive, worm-like creatures are bursting from the ground. Pairs of powerful fins allow them to glide through the dense atmosphere. They must have some type of colony underground.

The command below will trigger the "Endless Rock" event in Stellaris:

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

• Continue surface observations.
  • Leads to event: Sky Plankton
• Explore the tunnels.
  • Leads to event: Tunnels

Stellaris events fire in chains — one event leads to the next. Here is how Endless Rock (astral_rift.1800) connects.
