Voss

Voss is a traitor forge world (later purged) that declared for the traitors and surrendered its production to Horus. It sent an expeditionary force under Archmagos Ferrok Trahn to support the Sons of Horus (Vheren Ashurhaddon) in an attempt to retake Cthonia. A separate world from the loyalist Voss Prime (home of Legio Invigilata), with which it must not be confused.
