The Siege as five wars
Sol, the walls, the Titans, the Webway, the deck. “The battle for the Palace” is a harmful metonym: five different wars, each with its own fronts, tempo and winners, run at the same time.
Events of the theme
- The Solar War Traitor victory
The traitor fleet fought its way through the outer defences of Sol — a system of five concentric Spheres of Dorn.
- The Siege of Terra Pyrrhic loyalist victory
The culmination of the Heresy: Horus’s armada descended on the Solar System and besieged the Emperor’s Palace on Terra.
- Fall of the Lion’s Gate Spaceport Traitor victory
The Lion’s Gate Spaceport — the most powerfully defended — fell to the traitors, and the greater part of the sprawling Magnifican came into their hands.
- Mortis · the Titandeath of Terra Traitor victory
Horus threw Legio Mortis, the Sons of Horus and the Dark Mechanicum at the Mercury-Exultant kill-zone before the Exultant Wall. ~50 engines of Legio Ignatum with Imperator-class Titans held, but…
- Magnus Defeated in the Webway Loyalist victory
In the Webway tunnels beneath the Palace Vulkan met Magnus the Red and overcame him.
- Death of Sanguinius · the Emperor against Horus Loyalist victory
Horus lowered the shields of the “Vengeful Spirit”, luring the Emperor. Sanguinius reached him first — and was killed, refusing to betray the Emperor (thus the Black Rage was born).
How to look in the atlas
- “Siege” mode → “Siege phases”: the five layers are separated as standard; this is the only mode in which they do not merge.
- Time slider 14.02 (Pluto) → 14.393 (the Eternity Wall spaceport) → 14.5 (Mortis) → 14.587 (the Webway) → 14.593 (the deck).
- Rail → “Legions” → IV and VII: two schools of siegecraft on a single wall.
- The dossiers of Dorn and Perturabo side by side — the count is kept not in heroes but in timetables.
