From the back cover:
This volume collects all the battle-loving races, classes, and feats from Monte Cook's Arcana Unearthed variant player’s handbook. Use them to enhance your own d20 System games. You can use everything in this book alongside the 3rd Edition or revised 3rd Edition Player’s Handbook.
Quicklings, giants, litorians, and sibeccai. Champions, oathsworn, mage blades, totem warriors, unfettered, and warmains. These are the followers of the Way of the Sword. This 53-page book will expand your available roleplaying options dramatically. Here’s what you’ll find inside:
• Chapter One: Races:
Five all-new races. Some of them have special racial level progressions you can take like classes to gain unique racial abilities. Most of them start out as viable 1st-level characters, either with traditional classes or racial levels.
• Chapter Two: Classes:
Six brand-new core classes. Balanced to work together, they cover all the traditional combat-oriented “roles” you enjoy in fantasy games, but in a very different way
• Chapter Three: Feats and Talents:
In addition to traditional battle-themed feats, this chapter offers two new types: the talent, which you can choose only at the start of the game, and the ceremonial feat, which you can take after performing certain rituals.
