Ryza is a Forge World of the Imperium.^[1]

Overview

It is a formidable world, known for its plasma weapons and vehicles mounted with them, such as the feared Leman Russ Executioner (which is no longer produced by any other Forge World)^[1]^[2b] and the Stormblade Super Heavy Tank (which was first developed on Ryza).^[2c] The Forge World is home to the Titan Legion known as the Legio Crucius (a.k.a. the Warmongers).^[2a]

Ryza's approach is defended by an artificial moon known as Ryza Secundus. It is large enough to hold an entire Expeditionary Fleet of the Great Crusade. Today, the artificial celestial body is inscribed with the names of 12 House Vornherr Knights which fought to the end to defend it during the Defence of Ryza in the Horus Heresy.^[7]

History

At some point, a cult of Tech-Priests known as the Omnissiah Igvita (or "Life Blood of the Omnissiah") was founded on Ryza and dedicated itself to the study of all Plasma technology.^[7] By the end of the Great Crusade, Ryza stood second only to Mars in power and prestige among the Martian Mechanicum. Its production capability, specialty in Plasma manufacturing, and strategic location allowed it to be one of the central points for the Imperial expansion into the eastern Galaxy.^[7] During the Horus Heresy Ryza became known as a loyalist bastion in the East, leading to it being assaulted by the Dark Mechanicus. In the battle that followed the loyalists prevailed, though over 4/5ths of the planets infrastructure was destroyed.^[7a]

Ryza has been attacked by not one but two Ork Waaagh!s — Waaagh! Grax^[3a] and Waaagh! Rarguts.^[6] During the 13th Black Crusade though, Waaagh! Grax was finally defeated, but disaster struck the Forge World in the aftermath of the Great Rift's creation and Ryza soon found itself invaded by hordes of Daemons. Now only the presence of the numerous Astra Militarum Regiments that were originally sent to deal with the Ork Waaaghs! have prevented the Forge World from falling to the forces of Chaos.^[5]
