From the publisher's website:
This lavishly illustrated visual guide explores the magical, medieval fantasy world of Eberron. Climb aboard an elemental airship and visit wondrous locations, from the soaring spires of Sharn and monolithic mountain strongholds of the Mror Holds to the cyclopean ruins of Xen’drik and the gleaming glaciers of the Frostfell. See the world like never before and discover its many secrets.
If you’re a fan of fantasy artwork and literature, the An Adventurer's Guide to Eberron makes an excellent addition to your library or coffee table. It brings the world of Eberron to life visually and gives non-Eberron players a glimpse into a rich world of magic and mystery.
