The Farm
A paradise world somewhere in the Segmentum Solar, and not too far from Holy Terra, this planet is a highly secret Inquisitorial holding. Used as a place of convalescence for those Inquisitors who have gone a bit funny due to working too hard, or as a more permanent home for those who are unable to do their duty due to infirmity.
A rather unique place, the different landmasses are used to accommodate the different philosophical factions, so that peace may be kept. So the Puritans live in the northern hemisphere, and the Radicals stay to the south. The Amalathians, Thorians, and Ardentists are kept separate from the Anomolian Beholders and Recongregators, everyone is kept well away from the Xanthites, and if there are any Isstvanians there they aren't telling.
It is the only paradise world in the galaxy to receive regular shipments of heretics, traitors, and Xenos, so that even in old age the residents can still practice their favourite hobbies, meaning there's always a warm fire burning somewhere, and the sound of happy laughing Inquisitors and gunfire is a regular occurrence.
