From the back of the book (translated from German):
All over Europe, mere mortals strife to do the Lord’s will – whatever it may be. For this, they cannot build on heavenly powers; instead, they trust in God’s mercy and the skills they have been taught during their education. Whether it is in the isolation of a monastery at the edge of civilization, in the busy crowds of an Order’s metropolis, in the focus of attention of many or under the seal of secrecy – without the mortal servants of the holy Mother Church, life in Europe in the 27th century could not be imagined.
Mater Ecclesia reveals the way of life, the dogmas and rites of the servants of the church, tells of secrets that only known to a handful of initiates and makes the heroes in the shadows of the Engel real to the players.
Various hooks for exciting stories await you in the pages of this book. Stories, that will enhance the atmosphere of your Engel chronicle and allow for views of the mechanisms of the greatest institutes the world has ever seen.
