World at War
This book provides an unusual combination of an in depth and comprehensive guide to all major civilisations in Creation. Each chapter is a description of one of the directions of Creation finishing with the Realm with details on all aspects of how the cultures in that direction fight, what problems they face and examples of their military units. They also include to predominant directional military gods and detailed rules for the complications of fighting in each direction. Unfortunately they don't really go to town on naval warfare, I was expecting something different since it's such an unusual arena of conflict and rules for fighting with vehicles are included in Wonders of the Lost Age rather than in this book. This is an important point since there's a long list of conventional vehicles in the back of Scroll of Kings as well as an armoury of new equipment including artillery.
Covering the entirety of Creation (including the supernatural creatures that live within it such as the Lintha and Black Fleet Spectre Commandos ("Deeeaaathhhhh") who are catapulted into battle) keep this book interesting and you can base the army of any ally of foe you're likely to meet on what is in here. Smaller, more esoteric cultures are covered in the Compass of Terrestrial Directions series.
