Composition3

The Imperial Knights march to war as a banner of towering war-engines — two to four plasteel-and-adamantium titans, each a multi-Wound walker that strides over the battlefield and crushes rival soldiers underfoot. Where other forces field ranks of bodies, a Knight Household fields engines, and asks each one to be worth a whole warband.

Every war-engine is obscenely durable, wearing an armoured ceramite hull and shielded by the directional Ion Shield — an invulnerable field the pilot swings to cover a single arc each round. Beneath the striding legs runs a thin household crew of human Sacristans, who dart between the feet to weld a breached hull and re-raise a downed shield. The titans fight by facing, arc-of-fire and the titanic stomp: they win every exchange their declared shield can reach, and lose every footrace across the ground.

The Household is few, and each of its warriors is a cathedral that walks and kills — but a cathedral cannot stand in two places, and its shield faces only one way. Left to fight surrounded, out-marched and swarmed from the flank and rear, a war-engine is only its fixed hull against the flood, and even a titan of ten thousand years can finally be pulled down.

The Imperial Knights are the handful of titans that out-fights the horde and loses the footrace. This House marches to war not as a gang of bodies but as a lance of two to four plasteel-and-adamantium war-engines, each a multi-Wound walker that strides over the battlefield and crushes rivals underfoot.

Every engine is obscenely durable and defended by the Ion Shield — a directional field for which the pilot declares one facing at a time, so the open flank and rear stay a seam a foe can exploit. A thin human crew of Sacristans scrambles beneath the legs to weld a torn hull and re-raise a downed shield, the household's only healing and never quick enough to save them all. Fighting by facing, arc-of-fire and the crushing stomp is the whole of what a Knight is — a way of war no other House brings to the field.

A Knight household grows one titan at a time, only on hard-won Reputation, and it is the single source from which the wider Imperium requisitions a war-engine when the war is worth marching for.
