Sub-sector Octavia

Sub-sector Octavia is a Sub-sector of Segmentum Ferus controlled mostly by the Imperium of Man. Notably, it is the home of the Fire Scorpions Chapter of Space Marines, and its capital is the Atlas System. It also has the dubious distinction of playing host to a system considered by Imperial authorities to be irredeemably corrupted by the forces of Chaos, the Ivera System, which Nurgle sees as part of his garden.
