Editing The Markian Pact (section)

==The Hektor Heresy==
When Hektor began his campaign to undo the Emperor's works, the entire galaxy erupted into civil war. Segmentum Pacificus was devoid of marines both traitor and loyal, but nevertheless it was embroiled in conflict between Imperial Mechanicum and auxiliaries, and their rebel counterparts. At the center of the Pacificus theater were the forces of the Al-Sherar Sector, especially the Markian Pact. Almost as immediately  as the Hektor Heresy began the Al-Sherar Sector was invaded by traitors on three sides by Solar Auxilia, rogue Mechanicus, and other renegades. With many grand corps outside the sector and the armies of Ciban and Al-Sherar occupied, the Markian Pact stood only with themselves and what Ghalhal could provide.
