Changes

When the Imperium arrived during the [[Great Crusade]], Ryza peacefully assimilated into the domain of the [[Emperor of Mankind|Emperor]]. 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]].{{Fn|7a}} Its power and hoarding of advanced plasma technology creatures created some tensions and suspicious with Mars, leading to the world strengthening its forces in preparation for conflict.{{Fn|8}} This proved to be fortuitous, as 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 [[Defence of Ryza|battle that followed]] the loyalists prevailed, though over 4/5ths of the planet's infrastructure was destroyed.{{Fn|7b}}

Ryza has been attacked by not one but two [[Ork]] [[Waaagh!]]s — [[Waaagh! Grax]]{{Fn|3a}} and [[Waaagh! Rarguts]].{{Fn|6b}} During the [[13th Black Crusade]] though, Waaagh! Grax was finally defeated, but disaster struck the Forge World in the aftermath of the [[Great Rift|Great Rift's]] creation and Ryza soon found itself invaded by hordes of [[Daemon]]s. Now only the presence of the numerous [[Astra Militarum]] [[Imperial Guard Regiment|Regiments]] (including [[Catchan Catachan Jungle Fighter]]s){{Fn|9}} that were originally sent to deal with the Ork Waaaghs! have prevented the Forge World from falling to the forces of [[Chaos]].{{Fn|5}}
