The 23rd Grallian
Soldiers recruited from Grallia are known for their incredible devotion to the Imperium at large. Their legendary loyalty is also their greatest curse. Since the ministorium knows well they have little to no risk of corruption among their ranks, regiments from Grallia are frequently deployed to areas tainted by chaos or at risk of heretical uprisings. The 23rd regiment was no exception and so were deployed on Dargon Prime as a garrison to bolster the already very capable PDF forces. During the early hours of the Mutant Ascension it seems the entire garrison force was overrun after being massively outnumbered by Mutant Rebels. The armory stores in their barracks are fear to have been looted for the benefit of the Mutant Ascension.
