Segmentum Ferus

Segmentum Ferus is the fictional Segmentum where all Gridmark lore takes place. It is a fringe section of the Imperium of Man notable for its diversity and deviance from Imperial norms.

Humanity isn't the only race that lays claim to this part of the Milky Way, however. Several Xenos races including the Tau also call Segmentum Ferus home, and war between competing factions is waged constantly.

Notable Sub-sectors:
 * Sub-sector Imago Temptat
 * Sub-sector Lacerta
 * Sub-sector Octavia
