Well, another Eberron book, and another winner.
The artwork in this book is awesome, the cover art, the chapter beginning and pictures throughout are all of consistent high quality.
The content seems to be well laid out, however the lack of index in reference books is becoming frustrating.
The book contains the following Chapters (you will need the TOC as there is no index...)
Introduction
Intro and overview, how to read the stat block etc.
Chapter 1: Travel
Reasons for travel, motivations for travel, (I especially liked the section on travel vs. teleport, which gives a range of situations in which travel not teleport is appropriate.), how to travel, modes of transport, travel encounters
Chapter 2: Tools of the trade
Elemental vessels, everything you wanted to know, how to construct, controlling bound elementals, freeing them and so forth. Airships, attacking airships, elemental landcarts.
Lightning rail, movement of, battles on and a useful lightning railcar map.
Stormships and wind galleons and other vessels.
The chapter then goes on to boarders, forged papers, funded expeditions, organisations and then has...
3 Prestige classes
Cataclysm Mage
A seer like mage who's desire for forgotten knowledge and prophecy leads to great power and greater risk
Thunder Guide
A sort of scout/ranger adventurer
Windwright Captain
Most likely an NPC class as it revolves around piloting elemental vessels.
Chapter 3: Points of Origin
(Containing 4 Map Sites)
Where adventures start, a few adventure hooks, a map of the docking tower at stormhome, a lightning rail station etc.
The Crimson Ship deserves special mention as an inventive and potentially exciting role-play side adventure.
Chapter 4: Midpoints
(Containing 4 Map Sites)
The places along the way, along with many further adventure ideas to go with them
Chapter 5: Destinations
(Containing 9 Map sites)
The final destination of the adventure, described in the chapter are several fairly well detailed locales. The Khyber Dragonshard Cavern, the Shalquar Monastery and Tharkgun Dhak appeal particularly to me.
Appendix: Ancient Treasures
Giant and Dhakaani Antiquities
Magic items from past ages, some cool new items and a new special material (Eldritch whorlwood)
The book is packed with adventure hooks, detailed maps and ideas.
Looks like it will be a fantastic game aid and the artwork is fantastic.
4 stars, possible 4.5, however the lack of index prevents a 5 star rating.
