The Cult of Sarnath

Originally a Mechanicus Explorator Mission sent out from Weyland in 912.M39 to investigate pre-Imperial ruins reported on the Dead World of Sarnath. The planet proved to have been inhabited both by Humans and xenos of a physically repellent but technologically advanced culture. Nearly two millenia of exploration, discovery and back engineering has lured the members of the mission much farther from Mechanicus orthodoxy then they realize. A fact they have successfully hidden from their superiors on Weyland.
