The Caretakers

We have found the caretakers of this place. More accurately, we have found what remains of them. A nearby room is littered with corpses. Their limbs have been cleanly separated at the atomic level by some unknown force. Some of the carcasses are half-fused inside of the walls. A clutch of mostly dissected eggs is present on a central examining table. One of remains intact. Taking the caretakers' remains back for proper study should provide some insight into what happened here.

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

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

• Open an egg.

Stellaris events fire in chains — one event leads to the next. Here is how The Caretakers (astral_rift.2015) connects.
