The Adepta Sororitas has always lacked a good tank. Before his death Sabastian Thor took measures to change this. He had the Adaptius Mechanicus constructed a true tank for the sisters, the finial result was the Purifier. The Predator Purifier sports a turret mounted Fire Cannon. This cannon lauches balls of fire the explode on impact, killing or catching victims on fire. If anyone gets to close to the tank the sponson mounted heavy flamers make the pay with their lives.

The Purifier has rid many a world of heretics and tyranid contamination. the Predator Purifier has become one of the most feared tanks in the Imperium
