Boreal Cohort

The Horus Heresy

Masters of the void siege and the boarding action, raised from frozen orbital stations to fight where vacuum and killing cold slay the unwary.

Contents

Raised from the frozen void-stations and ice moons of the outer dark, the Boreal Cohort were masters of the most unforgiving warfare the galaxy could offer: the siege and boarding actions fought in vacuum and killing cold. Where other cohorts specialised in the open battle, the Boreal made their name in the airless labyrinths of void installations, star forts, and the drifting hulks of dead ships, environments in which a single breach in one's armour meant instant death and only the disciplined survived. Their soldiers trained relentlessly for the boarding assault, drilled to fight through darkness and depressurisation with the same cold efficiency they brought to any battlefield, and their Veletaris were counted among the finest void-storm troops in Imperial service. Clad in heavily sealed plate and armed for the brutal close work of the corridor and the airlock, the Boreal Cohort could take an enemy vessel or fortress that commanders had judged impregnable. They remained loyal through the Heresy, and their grim expertise proved bitterly valuable in a war fought as much among the stars as upon the ground, wherever a rebel-held void station or captured warship had to be stormed and cleansed compartment by bloody compartment.
