Explorer's Handbook

Another Eberron handbook, another decent source of information. This one is set up so it can serve equally as a handbook for players wanting more information on traveling in Khorvaire or across Eberron and as a source for DMs looking to get their players moving.
'Explorer's Handbook' goes in depth into how the various modes of transportation - airships, lightning rail, wind galleon - work, not just how much they cost. There are plans for the different ships, cabins, decks and how a character can operate them. This is a huge improvement on the sketchy details provided in the Campaign Setting
Transportation can be a serious problem with campaigns, but this book turns them into opportunities for additional interaction with guilds and organizations like the Dragonmarked houses and other more supernatural encounters. Locations covered in the book are divided into three sections : Starting Points, Midpoints, and Destinations. These are not as full of detail as I would have liked. Overall, a good addition to the supplements.
