The Forsaken's Folly

The Forsaken's Folly was an Imperial castigation campaign conducted by the Hammer Guard Space Marine Chapter against their traitorous, former kin of the Forsaken Hammers Chaos Warband in the Gallilean System.

Background
In 097.M42, after several decades of searching for their traitorous kin, the Hammer Guard were alerted to the presence of their wayward brothers by another chapter, the venerable and stubborn Brazen Dragons. Gathering their forces, the Hammer Guard deployed all available companies to the Gallilean System, where the Brazen Dragons had reported engaging the Forsaken Hammers. Within the month, all but the 5th and 8th Companies were orbiting Gallilean Prime.

In a brutal and bloody war, the Hammer Guard engaged their lost kin, initially without the upper hand as the Forsaken were revealed to have allies clad in black & grey. Eventually, however, Dominum Custodem Stormfury led a strike into the Forsaken defenses that proved successful, pushing into the Forsaken's bastion and overwhelming the traitors. In the conflict, the wounded Stormfury, aided by Clericus Charos and four of his Legates, engaged the Forsaken Chaos Lord Decarde Karrova, reinforced by his mysterious allies and sorcerers. This epic battle would result in the death of Karrova and the destruction of most of the Forsaken, at the cost of Dominum Custodem Stormfury and 250 Hammer Guard Astartes, with many gravely wounded.
