first printing of the core rulebook was soft cover and was later reprinted in a hardcover format. An extensive line of Tribe 8 books was printed, consisting of "Word of" books, cycle books, Legend books, and setting sourcebooks. The "Word of" books focused on the details of the Tribes and their society. Cycle books were a linked series of adventures that built up an epic story of the Fallen and their search for destiny. The setting sourcebooks covered lands and places in detail, expanding the world – including books giving more detail on the Z'bri, the River of Dream, and the Outlands. Finally the Legend books were short series of stories with adventures not connected to the meta-plot of the cycle books. Tribe 8, 2nd edition was printed in 2004 as a soft cover book that used the Silhouette Core Rules. Thus, unlike the 1st edition, it was not a complete game and needed the Silhouette CORE Rulebook to play. The second edition moved the setting from Vimary to Capal (another city), advancing the history of the world by 15 years. It also finally revealed the whole course of the metaplot, allowing Gamemasters to weave their own stories rather than wait to find out how the world would change. Though plans to follow up the second edition with more supplemental books have been discussed, there have been no further releases yet. Since 2004, many of the Tribe 8 rulebooks and supplements books are available as PDF downloads on DrivethruRPG. Publications Rule system Tribe 8 uses Dream Pod 9's own Silhouette game engine. The latest edition of the Silhouette rules is sold separately as a book titled Silhouette CORE Rulebook, which is needed to play the second edition of the Tribe 8 roleplaying game (the first edition rulebook included its own version of Silhouette). Silhouette is a realistic, simulationist system that defines characters in terms of 10 base attributes (agility, knowledge, etc.), 5 derived attributes (health, etc.), and a variety of skills. Skill rolls make up the backbone of the system, which focuses on effect-based speed of play over grainy detail. The core mechanic involves rolling a number of 6-sided dice, taking the highest result and comparing it to a set threshold number. If the result is higher than the threshold the test is a success; if it is lower the test is a failure. The margin by which the test
