The stalwart Solar Auxilia of the 31st Millennium are the finest soldiery among the unaugmented armies of the Imperium, second only to the Space Marine Legions. It is upon their backs that many of the Great Crusade’s successes were built, and in the bloody crucible of the Horus Heresy, they fight in their billions, both for and against the Imperium they helped create.

This book is an essential guide for anyone who wants to command Solar Auxilia armies in Warhammer: The Horus Heresy. It contains the rules you need to field the various troops and war machines of the cohorts, whether they are loyal to the Emperor or the Warmaster. It includes Detachments, Wargear, and special rules which make the Solar Auxilia a unique force on the tabletop.
