How do you open a portal to another place? How do people use proto-dimensions for rapid movement to a location miles away. If there is such a thing as a doorway to another reality, can it be locked? Why is it easier to dimension walk from Demonground? Are there safe havens in the proto-dimensions? Where did the proto-dimensions come from? Are there other worlds in the proto-dimensions, other races -- allies or enemies? What are the Plaguelands? These questions, and many others, will be answered in the Proto-Dimensions Sourcebook, Volume 1. There are rules for proto-dimensional travel by means of empathic power or by the use of technological devices far beyond the ability of humans to create. All the details of dimension-walking are covered, telling how to stay alive while doing it. Players will learn how to build an interdimensional portal -- or how to destroy one. Further, the Proto-Dimensions Sourcebook describes 12 different proto-dimensions, ranging from tropical paradise to a sulphurous hell, from the vastness of a perpetual sky to surreal landscapes populated by creatures from out of a nightmare, from a world where everything is normal except for the color to a world where nothing is as it seems. If you are a Dark Conspiracy referee, you will be able to incorporate the proto-dimensions into your campaign with relative ease. If you are a player, your character can now take the battle to the enemy's backyard.
