Overview
Gathalamor is a cardinal world where the dead outnumber the living and the shrines outnumber both.
Its catacomb-cathedrals anchor Ecclesiarchy authority across the southern approaches to Terra.
In the Rift era its sanctity became strategy, as war came seeking the roads to the Throneworld.
M41 and M42 status
Cardinal world of tomb-shrines and pilgrim traffic.
Contested shrine world; faith weaponised in its defense.
