After a thorough reread and several backchecks, I have had to readjust my initial review. This book is superb. The perfect companion book for Eberron. It adds to all the lore of the world without contradicting itself and gives so much depth. The only thing that worries me is the binding. Not sure how well it will hold up to prolonged and repeated use. 5 out of 5 for content though.
[5 of 5 Stars!]
