On the zoo world of Indiga, the Praefects have the unpleasant task of protecting the planet’s natives from the the dangerous animal life that prowls the surface. The giant predators had once been the pride and joy of the pompous governor, Constantine Principa Argoy, who spent the planet’s copious mineral wealth on the purchase of breeding pairs of every dangerous creature he could acquire from planets across the Segmentum. Unfortunately, after a catastrophic earthquake shattered the governor’s zoos, the giant animals escaped into the wilds to breed and hybridise with each other.
Because of this, the Indigan Praefects have become experts at slaying large and dangerous beasts, and their reputation is such they have been requested as reinforcements in multiple war zones assailed by Tyranids. Where these requests have been honored, the Praefects set about eradicating the xenos fiends with practised efficiency. Veterans who have faced the Tyranid swarms help to drill new recruits on how to combat the creatures.
