Praetorian of Dorn (The Horus Heresy)

The Horus Heresy reaches the Solar System - will the defences of Rogal Dorn and his Imperial Fists hold against the onslaught?

Recalled from the Great Crusade after Ullanor, Rogal Dorn and the VIIth Legion were appointed as the Emperor s praetorians but only after the Warmaster s treachery was revealed did the full extent of that sacred duty become apparent. Now, the Solar System comes under attack for the first time since the war began, and many of the seemingly impregnable defences wrought by the Imperial Fists prove inadequate. With all eyes fixed firmly upon this new threat beyond the gates of Terra, who will protect Dorn from the enemy within?
