Castille, an abundant country full of contradictions, home of the church yet with a thriving scientific community despite church opposition, friendly and welcoming people unless you happen to be a foreigner, full of celebrations and fun amidst cruelty and hardship. Here you find passion, loyalty and devotion to duty. Cherishing tradition, the people of Castille embrace life to the full... but now they are at war, and everything seems to be teetering on the brink of destruction. The Introduction sets the scene before launching you into four sections designed to present Castille as a living, breathing element of your game world.
First up is Castille. Here you can read about the nation's long and noble history, with culture and government, noble families and interesting places all covered. Its history is one of repeated conquest, just about every civilisation that lays claim to greatness has invaded at some point (and now Montaigne are trying to do the same...). We meet the eight great noble families and a whole slew of lesser ones - plenty to conjure with if you want your character to come of noble blood. The regions are explored with concise yet informative notes (a map might help, here...) and there's plenty of culture too, dance in particular. Liturature, painting and music also play a major role in the Castille cultural scene, while festivals and celebrations are part and parcel of everyday life. Less pleasant, perhaps, to outsiders is the local love for bullfighting... although the practice of injuring or killing the bull has been mostly eliminated from the sport. Daily life, clothing, etiquette and even food are also covered here.
There is also an extensive section on the Vaticine Church in this chapter. For some six hundred years, the Church has been based here and it looms large in virtually every aspect of life. There are tales of the Three Prophets (and mention of the Fourth, who is yet to come), church history and more. Intellectual and scientific events are also covered - partly because they annoy the church so much.
Then Hero presents a gallery of the great and good, the movers and shakers from many walks of life, starting with the Good King Sandoval himself - a 16-year old boy who had never expected to inherit his throne but is doing remarkably well. Nobles, churchmen, military and others are also well-represented with descriptions of who they are and what their aims in life might be. Plenty of people to meet, influence, toady... as the party chooses.
Next, Drama is the 'rules bit' with new backgrounds and skills, new swordsman schools, new advantages and more. There's also a new (and destructive) form of sorcery called El Fuego Adentro, if you want to try that out. There's also some neat new equipment (did you think a cloak was just for keeping warm?) and some rules for building, defending and attacking fortifications.
Finally, Brotherhood contains information on role-playing Castillians, be they a cherished character or a slew of NPCs encountered in the course of the party's adventures. Life, a Castillian's very existence, revolves around your family and passion. Approach everything, large or small, with intensity and gusto. Live large. There's also material for the GM alone. This includes all those dark little secrets the fellows in the Heroes chapter would rather you didn't know, full stat blocks for each of them, and a couple of new monsters - one of which is a bull, should anyone wish to try their hand at bullfighting. There is also a map of the city of Altamira and a couple of ships.
This work is full of flavour, packed with information to bring Castille to life in your game should the party decide to visit - or to give a character from there a good feel for his homeland. A map of Castille would have been an advantage, so you could see how the various places relate to each other, but that's about the only quibble. If the plot heads for Castille, have this work to hand.
