Campaigns of the Age of Darkness: The Martian Civil War

Having declared its secession from Imperial rule at the very dawn of the Horus Heresy, Mars sat like a viper upon the doorstep of the Loyalist Throneworld – a locus of industry which toiled ceaselessly in preparation for the inevitable Traitor assault upon Terra. Loyalist incursions throughout the civil war would attempt to stymie these efforts, but eventually, the power of Mars would be unleashed against the Sol System in a maelstrom of violence.
