The Evermore

The Sentinel was indeed hiding an entryway. It opens on a mezzanine of underground tunnels leading deep into …'s crust. There a sapient species of humanoids, native to the planet, prepared for their final journey in a set of beautiful ceremonial chambers. At the end of their mortal existence they abandoned their fleshy bodies for a virtual afterlife within a simulation of paradise contained on a single drive. At some point the entire population decided to move on to a digitized existence, leaving only a few behind, their minds uploaded to the Sentinels, condemned to guard their resting place forever. Perhaps this virtual simulation could lift the spirits of the masses. It certainly seems to hold some entertainment value.

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

When this event fires, you can choose between these 4 options:

• Purge the aliens and repurpose the simulation for our needs.
  • +300 Influence
• A virtual hunting ground... Now that's entertainment...
  • +300 Influence
• Replicate the technology. Let the aliens live in peace.
  • Start special project: Replicate the Evermore
• The aliens will make excellent lab rats. Commence the freak show.
