The Introduction paints the picture of lands reeling from a generation of wars, seemingly no family untouched, awash in mud and blood and destruction yet still proud. Desperation and hunger are side by side with those who do good and seek to serve others.
First, Eisen tells about the country itself. Ancient history tells of a race of intelligent reptiles, the Drachen, that founded a civilisation but then disappeared. There are still 'drachen' in the land, smaller (still impressively big, though) and not at all intelligent. Perhaps they are related to the ancients, nobody knows. Centuries passed and men came, fierce tribesmen to begin with, then sweeping empires, but always a land fragmented, with tribe immediate and important, more important than a distant empire. Then the marvelous metal known as dracheneisen was discovered... Faithful to the teachings of the church, Eisen sided with Castille when the Third Prophet arose there, but a bit over an hundred years ago, a freethinking monk called Matthias Lieber promulgated ideas that led to the Objectionists: people who believe in the faith but do not think the established church is doing the right things - concentrating on amassing political power rather than caring for people. This led eventually to a vicious civil war that has wrecked the nation, and caused the leading barons to split it into a confederacy of seven self-ruling kingdoms. Now people are attempting to rebuild the shattered nation.
Next, Hero introduces some of the movers and shakers of the land - people who could make useful contacts, powerful patrons... or the deadliest of enemies. Here you find descriptions, personalities, objectives... if you want stat blocks or to find out their secrets, these are in the GM section at the end of the book. This is followed by Drama, where new rules material is introduced, including backgrounds, equipment, skills and of course, swordsman schools. This includes clearly-diagrammed ways of using the distinctive zweihander sword. You'll also find rules for mass combat here, should you wish to stage a full-blown battle.
Finally, Courage comes in two parts. The first contains information in playing an Eisen character to effect, useful for players wishing their character to come from Eisen and to GMs needing to manage Eisen NPCs. Next, GMs are regaled with secrets including the fate of the Drachen and the nature of dracheneisen, as well as those of the various kingdoms and the NPCs introduced earlier. There's a map of one town and some building plans - a map of the entire country showing the various kingdoms would have been nice - and assorted monsters, too.
Overall, there's a lot packed into this and should your adventures go near Eisen it will prove an excellent resource. Indeed should your party want to head in that direction, there's plenty to spawn ideas for plots there!
There are enough differences between the kingdoms that they appear to be completely separate nations, yet they are all clearly part of Eisen as well. Each is described in considerable detail, complete with interesting places to visit, local customs and laws, organisation and so on. And then there's Freiburg. A sprawling city-state with a very laid-back ruler and minimal law, a refuge for many, a cosmopolitan free town (and one worthy of its own supplement!). There are notes on general culture and on dracheneisen, including the secrets of its forging (or at least, details of who has those secrets!). Sculpture, opera, and literature are the prevalent art forms. You can also read how Eisen does war, learn of the mercenary warbands, or look at Eisen science and religion. Nationally-observed customs are also included, along with legends and notes on the 'monsters' that plague more remote corners of the land.
