Overview
Mordian is an austere hive world whose regimental culture is built on precision, formation, and public discipline. Its cities teach obedience under darkness, ration, and parade-ground severity.
The world turns social rigidity into battlefield utility. The Iron Guard are not celebrated for flexibility; they are valued because a straight line that does not break is sometimes the only theology command requires.
