Perditus System

The Perditus System is an Imperial planetary system. No segmentum or coordinates are recorded. It contains the worlds Perditus Ultima, an Adeptus Mechanicus research station, and Perditus Secundus.

During the Great Crusade, the Dark Angels and Death Guard brought the system into the Imperium, and a classified Mechanicum research station was established there.

During the Horus Heresy, the system was the site of a skirmish between Death Guard and Iron Hands elements, after which Lion El’Jonson led a task force from Balaam.
