Two Lancastrians and two Yorkists draft cards that give them control of major towns, nobles, bishops and royal castles. Income generated by these enables them to raise armies and to bribe nobles, bishops and ship captains to change allegiance. Players then use secret planning and simultaneous deployment to gain control of the six areas in England and Wales and, hopefully, enough votes in parliament to crown their royal heir as king.From the back of the box: Journey back to England, 1450, just prior to the outbreak of the bitter civil war between the Royal Houses of Lancaster and York. Heny can be randomly generated as you play or placed carefully ahead of time. It is written to be of use to both experienced and inexperienced Game Masters, particularly those who (for whatever reason) find themselves short on time or creativity. This book includes 100 Bits of description, and 20 Shards. The Bits are small pieces that can be stuck in, anywhere a little description is needed, and are numbered so they can be used randomly. Shards are slightly larger, and may depict a particular place or event, or set a feel for an area. The material is also indexed a number of ways to allow a GM to easily find a description to fit a particular circumstance. Each Bit is also provided in index card format for ease of use by Game Masters.As a special bonus, we have included a brief description of the way caverns are formed and information on the real-world and fantasy aspects of cave exploration. There are also two new Swarms - cave beetles and serpents. In addition, some descriptions are graphically depicted in the excellent interior art by the Carmona Brothers.'Bits of Darkness: Caverns' uses material from the SRD, but could be used in any fantasy setting with very minor modifications. - BoardGameGeek
