  • Davin: The Warmaster’s Wound 004.M31 · Davin · Segmentum Ultima

    The uprising on Davin’s moon, the anathame’s blow, the Serpent Lodge. Horus returns “healed” — and already an enemy of the Imperium. By this point the Warrior Lodges have been…

  • The Burning of Prospero 004.M31 · Prospero · Segmentum Obscurus

    Magnus breaches the Webway, trying to warn the Father about Horus. The Emperor sends Russ; Horus swaps the order. The Thousand Sons perish as a civilisation, the Wolves become…

  • The Isstvan III Atrocity 005.M31 · Isstvan System · Segmentum Ultima

    Four Legions land their own loyalists on the pretext of suppressing a rebellion and burn them with the Life-Eater. Garro escapes aboard the Eisenstein. The Heresy becomes open.

  • The Drop Site Massacre 006.M31 · Isstvan V · Segmentum Ultima

    Three loyal Legions land against four “open” traitors. The second wave — four “allied” Legions — closes the ring. Ferrus dies; the X/XVIII/XIX cease to be armies.

  • The Signus Campaign 006.M31 · Signus Cluster · Segmentum Ultima

    The Blood Angels are drawn away from Isstvan into a trap of the warp. Ka’Bandha, the Thirst, the near-fall of the IX. Sanguinius defeats the daemon and does not reach the drop…

  • Calth and the Shadow Crusade 007.M31 — 008.M31 · Ultramar · Segmentum Ultima

    The Word Bearers strike Calth as the heart of the XIII’s logistics. The Word Bearers’ ritual on Calth — and the massacre across the Five Hundred Worlds that follows it — gives…

  • The Thramas Crusade 007.M31 — 009.M31 · Thramas Sector · Segmentum Ultima

    Years of the Lion’s and Curze’s hunt on the eastern edge. There is no “single battle” — there is the mutual destruction of fleets, Tsagualsa, an exodus after which the Lion will…

  • Imperium Secundus 008.M31 — 011.M31 · Ultramar · Macragge · Sotha

    The Ruinstorm cuts off the east. Guilliman proclaims a Second Imperium; Sanguinius becomes Imperator Regis — regent-emperor; Guilliman takes for himself the civil authority of…

  • The Battle of Molech 009.M31 · Molech · Segmentum Solar

    Horus takes a world where the Emperor once struck a bargain behind the veil of the warp. House Devine splits apart. The Warmaster emerges with a power that makes him a vessel of…

  • The Battle of Beta-Garmon 010.M31 — 013.M31 · Beta-Garmon Cluster · Segmentum Solar

    The threshold of Terra. Years of escalation (from Nyrcon to “Titandeath”) grind down the Titan Legions of both sides. Whoever has lost the field has no right to meet Sol in open…

  • The Battle of Tallarn 010.M31 — 011.M31 · Tallarn · Segmentum Tempestus

    The Iron Warriors sterilise Tallarn with a virus and get the greatest tank war of the age. Perturabo is looking not for a flag over the desert but for what is hidden beneath it.…

  • The Solar War and the Siege of Terra 013.M31 — 014.M31 · The Solar System · Terra

    From the outer spheres of Sol to the Golden Throne: the fall of Pluto and Luna, the plague, the spaceports, Saturnine, Perturabo’s departure, the Eternity Gate, the boarding of…

    The counter-offensive after the death of Horus: the traitors are driven towards the Eye, Mars is liberated, Caliban perishes in the Lion’s domestic war, Skalathrax finishes off…
