Quarantined Worlds: Argoth, Kaggeran, Rheelas (Canis Salient)

The Canis Salient is the oldest Imperial warzone within the Jericho Reach. Located to coreward, its first battles were fought in a Crusade to liberate dozens of human-inhabited worlds from Tau expansion.

Initial progress was good, and in many ways, the Crusade fell victim to its own success. The opening of the Acheros and Orpheus Salients drew manpower and ships away from the Canis salient, while the Tau received substantial reinforcements from beyond the Reach. In time, the Tau gained the upper hand, and Crusade Command was forced to make from hard decisions.

Worlds that could not be brought to compliance would instead be subject to "strategic measures," meaning population centers and industry would be subject to massive orbital bombardment, as to deny it to the enemy. This freed up soldiers and ship for service on the main Greyhell Front.

Three worlds within the Canis Salient were deemed so valuable (and not hopelessly tainted) that they were quarantined instead of depopulated. The intention was always to return them to Imperial control, but it never happened. As Lord Commander Ebongrave became increasingly more paranoid, seeing Tau plots everywhere, he refused to lift the blockade, leaving the Quarantined World to die slow deaths.
