The book of chantries is an absolute necessity. Mages, like humans, are social beings. They require interaction with other Mages. The Book of Chantries allows mages and storytellers to focus on the social aspect. It allows players to group together to create a chantry or to even join the largest of all chantries, Doissetep.
In the book there are detailed descriptions of Tradition Chantries, Technocracy Constructs and Nephandi Labyrinths. Each of these includes information on story ideas, NPCs, Locations, Nodes, History, Art and much, much, more.
The book also has a section that explains how to create chantries. In this section are details of how chantries are defended, how sanctums work inside chantries, how nodes are added, and the horizon realms chantries can have. And many other bits and pieces.
The Book contains Information on a few rotes. This is probably the most useless page. The rotes are short, boring, uncreative, and a waste of space. On the bright side it only takes up one side of a page so it does not lower the over all value of the book to much.
There is also a short story called "Harvest Time". This centers on a Verbana hereditary chantry owned by the Crombey's. It is an OK story. It is original and an asset too anybody looking for a new idea for a story, however I did not care for the ending it suggested and take a different route every time I use it.
Altogether a great book! A page is wasted on rotes, but everything else more than makes up for it. A must have for every mage player and storyteller interested in chantries.
