Angels Porphyr

The Angels Porphyr is a Loyalist Space Marine Chapter that was founded in the 31st Millennium, though their specific Founding and genetic origin remain unknown. The Forge Moon of Keziah, in the strategically vital Agathon System, fell into an unnatural eclipse during which its population was driven to murder and madness in an endless night of horror. The dread forces of the Tenebrae and the Company of Misery reigned as dark kings amid the nightmare, and the baleful light of the “Witching Moon” that Keziah had become spread calamity and warp-tainted phenomena wherever it now fell, threatening the entire star system.
