Description

The End of the World. Characters in the very first episode of the critically acclaimed television series Jeremiah seek this enigmatic location. The New World equivalent to Shangri La, the End of the World is actually a real place. Known as Thunder Mountain, it is, in actuality, the Cheyenne Mountain Facility in Colorado Springs, Colorado. Or, at least is used to be.

Like the rest of the world, the Cheyenne Mountain facility was devastated by the Big Death over 15 years ago. Originally designed to withstand a nuclear attack, Thunder Mountain became home to NORAD and was later expanded to help in Homeland Defense during the war on terror. Thanks largely to one young boy, Thunder Mountain became a haven in a sea of chaos after the Big Death. Markus Alexander rallied the few children in and around Thunder Mountain and organized them as the rest of the world collapsed outside. Taking in stragglers over the years, Thunder Mountain only recently began to re-emerge into the world.

This sourcebook for the Jeremiah Roleplaying game covers the events that led to the founding of the current Thunder Mountain society, its re-emergence into the world, the creation of the Western Alliance and the key characters that made all this happen.

Chapter One covers the basic history of Thunder Mountain while Chapter Two details the layout of the underground facility. Chapter Three goes into greater detail on the communities and towns that rallied behind Markus to form the Western Alliance and the remaining chapters include new rules, skills, feats, and advanced character classes. Expanded rules for airborne movement and combat are included and all major onscreen personalities are fully detailed.
