Warhammer Fantasy Roleplay, 4e: Lustria Collector's Edition.
Embossed details picked out in gold foil and dramatic dark green details illustrate a decoration associated with the Solar Engines of the Old One Chotek. The spine of the book is rounded with raised hubs, and the paper edges are edged in gold, giving the impression of a prized tome that may contain the notes of an adventurer to the hostile continent of Lustria.
