The Storm of Faith is a highly mobile religious terrorist group born out of a break-off cell of the Sons of Heaven. The cause of the split appears to have been the Storm's dissatisfaction with the Sons' relative leniency in a number of religious minutiae, including the Sons' acceptance of humans into their ranks. As a result, the two groups have a great deal of bad blood between them, and have come to blows several times. The Storm of Faith is largely based within the Siakar Expanse, Iabuze and the Hades Gulf. While still mainly an issue to nearby ex-Covenant polities, with their mobility and ferocious hit-and-run tactics, the Storm are a non-negligible a threat to outlying Orion-side human worlds.
