The Partisans are secessionist rebels who live in the Untill marshlands of the planet Gereon.[1]
'Partisans' is the name applied to them by the majority Imperial population; their own name for themselves is 'Sleepwalkers'. Descendants of religious radicals amongst the early human colonists, they believe in an independent Gereon and resist the rule of both the Imperium and Chaos.
