Jerulas System

The Jerulas System is a long-isolated hive well on the Pacificus/Tempestus seam, rediscovered prosperous and uninterested in missionaries, then beaten into the Imperium by High Marshal Ludoldus's Black Templars. The Land Raider Crusader was born in those hive sieges.

Jerulas Station shares the well. Defenders claimed Dorn himself had designed the forts, which only made the Templars more determined. Some maps argue northern Ultima; this overlay keeps the existing combined-segmentum parent.

The Jerulas System still matters as the Crusader's birth well. Unofficial maps do not relocate the pin over a cartography argument.
