Secrets of Xen'drik is an accessory for the Eberron setting that explores the continent of Xen'drik, with its shattered cities and vast dungeons which hold the secrets of countless fallen empires. This book contains a comprehensive overview of Xen'drik and the gateway city of Stormreach. It includes new feats, prestige classes, spells, equipment, and magic items. It also provides encounters and magical locations that can be dropped into existing campaigns, as well as ready-to-play adventures, monsters, and villains.
Secrets of Xen'drik introduced the concept of encounter traps, which function more like combat encounters than normal traps, and later appeared in Dungeonscape in an entire chapter devoted to traps.
