Ania-Anga

"Though the materium itself shake from the enemies wrath, Ania-Anga must not fall. Though Armageddon burn and crack, Ania-Anga must not fall. Though the foes of mankind close in on us from beyond the stars, Ania-Anga Must. Not. Fall."

- Admiral Kaller to his fleet, rallying them in the defense of the Forge World Ania-Anga is one of the oldest Forge-Worlds in the Imperium and currently is considered one of the most valuable planets in the Segmentum Tempestus, approached only by the Hive-World Krieg. Such is it's importance that the sheer defenses throughout the system approach Cadia and Holy Terra itself. Unlike Mars and Lucius Ania-Anga produces no Tanks and very few las rifles. The closest thing it produces to Titans is Knights for the Knight World Maxhillain, and that is considered one of the planets lesser functions.

Ania-Anga produces something far more valuable than even the mighty Idols of the Omnisiah. It remains one of the few Forge-Worlds still capable of producing the Imperium's mighty vessels, from Frigates to Battleships with remarkable frequency as well as repair such vast machines. Considered an Invaluable resource for most if not all of the factions within the Imperium, from the Imperial Navy, to the Inquisition, it is constantly guarded from any possible attack.

Founding
The first origins of Ania-Anga go back to the Age of Strife. Through some unknown means the planets human population managed to survive the uprising of the men of iron far better than most. When the Adeptus Mechanicus discovered it during the height of the Great Crusade they were quick to claim it, as well as it's many STC fragments.

Later Ania-Anga proved to be far enough away from most of the fighting of the Horus Heresy than they were almost entirely unaffected by the Schism of Mars. The only noticeable effect was that the leaders of Ania-Anga lost trust in most of the rest of the Adeptus Mechanicus, this mistrust only deepened with the disappearance of the Primarchs.
