Finally it's here! This book was worth the wait. Lost Empires has it all. Well almost. Most of the magic items and artifacts ever published in previous editions for Forgotten Realms (Nether Scrolls anyone) and most of the spells (Sakkratar's Triple Strike maybe). There are 16 new feats most of which are pretty good and useful (Craft Scepter is nice (2 spells up to 7th lvl with 50 charges), Arcane Manipulation is even better (up to 3 higher lvl spell slots are devided to give you many more lower lvl spell slots). There are 5 prestige classes out of which I'd select Olin Gisir (an elven "keep the bad stuff hidden" arcane spellcaster - gets secrets similar to the Loremaster, but every 3 lvls). The best part regarding the spellcasting are 2 new epic seeds: Mythal Seed and Shadow Seed. And then a really detailed explanation on making mythals. Really nice. Some old (and dead) gods are presented and there are a few pages of info and tables on "what's in that ruin type of stuff." The information about various ancient and lost empires and how they impact modern Faerun is well presented. Every "empire" or "time period" (Crown Wars?) chapter starts of with a timeline, and then presents an overview of the most important features and historical information regarding the specific empire or time period. A number of present day sites are detailed and even some adventures or adventure sites are connected with each lost "empire". In short: If you liked AD&D 2nd Ed "Nethril: Empire of Magic", "How the Mighty are Fallen", "Cormathor: Empire of Elves" and "Fall of Myth Drannor" you're gonna like this book even more. Crown Wars, Nethril, Imaskari, Cormanthyr (Myth Drannor), Realms of the High Forest (Ammarindar, Delzoun, Eaerlann...), The Old North (Ardeep, Illusk...), The Impreial South (Tethir, Shoon Imperium...). Each "period" also has a very useful "Information table" that sets DCs for know (history) checks and explaines how detailed information should DM give to the players and there is also enough historical information that DM's won't have as many problems as they did in the past when players asked about certain "Lost Empires" after a good knowledge (history) check. In the end there is a monster chapter which gives some updated monsters and presents some new ones (Phaerimm, Helmed Horrors, Baneguards etc.). All in all worth the money spent.
