Antax is a vitally important Imperial Forge World located in the Vidar Sector in the Eastern Fringe of the Ultima Segmentum. As one of the sector's principal Forge Worlds, the forge-fanes of Antax are packed with archeotech vaults filled with all manner of arcane technology and, of course, thousands of weapons, stockpiles of deadly ordnance and armoured vehicles. Antax is responsible for supplying hundreds of Astra Militarum regiments and a dozen Space Marine Chapters with the arms and vehicles they require.
In 927.M41, Antax fell to the Orks of WAAAGH! Gutstompa. The Blood Angels quickly mobilised and assembled Strike Force Aphael, to battle the invading Greenskins. Though weary from their part in the war against the Necron World Engine, Captain Donatos Aphael turned his 2nd Company aside from its homeward path, and set course for beleaguered Antax. Just as the battle looked likely to go against the Blood Angels, they unleashed the fury of their Death Company.
Led into battle by the ancient Death Company Dreadnought Moriar the Chosen, Captain Aphael and his surviving Battle-Brothers crushed the reeling WAAAGH! Gutstompa, ending the threat to the Forge World amid the fire and blood of the campaign remembered as the Battle for Antax.
