Ancient shrine

Ancient structures are large rooms that contain ancient cryptosleep caskets, bug hives and mechanoids.

Rare things and artifacts, such as luciferium, psychic insanity lances or psychic animal pulsers can be found in these buildings.

They can spawn on any map tile, and can sometimes have multiple, or none at all.
