Forge World Ryza

Of all the forge worlds that toil in the Omnissiah's name, Ryza is the one whose genius burns brightest. Its Tech-Priests are the unrivalled masters of plasma technology and the magnetic containment fields that cage it, and many within the Cult Mechanicus rank its sophistication as second only to that of Sacred Mars. The pattern-weapons and reactor cores that leave its manufactories are coveted across the Imperium, and famed engines of war such as the Executioner and the Stormblade were first given form in its cradles.

This obsession is as much creed as craft. Since the long night of the Age of Strife the world has been shaped by a Cult Mechanicus sect that held plasma to be the literal lifeblood of the Machine God, teaching that in harnessing that seething power a Tech-Priest touched a fragment of the Omnissiah's essence. From this doctrine rose the Legio Crucius, the Warmongers, a Titan Legion armed to an unusual degree with plasma weaponry drawn from Ryza's vaults. When the galaxy tore itself apart in the Horus Heresy, the strength Ryza had gathered in its rivalry with Mars proved its salvation, and the Defence of Ryza passed into legend.

In the millennia since, the world has become a byword for defiance. Time and again it has been beset by titanic invasions and greenskin sieges that grind on for years without end, its plasma-fires holding at bay foes that would overrun a lesser forge. Ryza is proud, embattled and indispensable, its burnt-orange legions certain that the Imperium cannot do without the fire they alone command.
