Melchior System

The Melchior System is a Great Crusade compliance well in Segmentum Obscurus where Word Bearers and Luna Wolves still pretended they were the same Imperium. Melchior itself was the killing floor; sister rocks such as Beta Rigel II, DeCora Spine, Orpheo Minoris, Sagan, and Sagan's Moon share the charted well.

Argel Tal learned what a successful compliance costs here. The Sagan pin under this system is this Obscurus neighbour, not a second Maelstrom Sagan.

The Melchior System still matters as a First Heretic address. Unofficial summaries keep the Obscurus parent.
