When the armies of the Imperium march to war, they are often accompanied by Preachers – men of absolute faith who seek to bring righteous retribution to all those who fight against the Emperor of Mankind. In the Imperial Guard they are represented by Ministorum Priests, men who fight for decades with the common soldier and who dedicate their lives to the spiritual wellbeing of the army. They lead by example and gladly martyr themselves on blood-soaked fields – to them there is no higher calling than fighting alongside the Emperor’s armies.

Many Inquisitors are accompanied by a Preacher or Banisher, whose fiery catechisms are anathema to the creatures of Chaos. To Daemons, their Litanies of Purity are as deadly as a sword, causing them to suffer wounds that they would normally ignore. Ecclesiarchy Confessors have also been known to lead the Orders Militant – the Sisters of Battle – to war. They lead with such righteous rage that all around them are inspired to fight harder and better in the name of the Emperor. It is a foolish enemy who things they can out-fight a fanatical Confessor and his most loyal followers.
