I've been sitting on this for months, and meaning to get it posted. It doesn't have the artifacts, or the powers, but it is the rules to create the artifacts as done in Promethium Exxet. I can't guarantee there will be more of this book done, but I will try. Hope this is a good start, for those who are interested. Also, this chapter includes the new skills Runes, Alchemy, and Animism. Mostly they are skills used for creating enchanted objects, but they now officially exist.
