"Eggs" are the outstations occupied by members of Tania's tribe when living and working away from The Traigh. They are little living spaces that can be dropped off from their ships and buried out of sight. Almost entirely self-sufficient, extracting energy from the ground they are buried in, they are often extended with their cutting devices into the surrounding land, but the basic shell is the same. They have links to the Archive and a local system if they become cut-off from the Traigh for any reason."
They are genetically linked to the inhabitant. When they die, the egg seals itself completely and degrades over about six months, everything within it turning to solid rock.
