Plumbum is the Refinement of Lead, and is practiced by Prometheans who study the very nature and existence of themselves and of other Prometheans in hopes of finding clues to achieving Mortality. The Originists see the other Refinements as somewhat flawed, as many of the other Refinements focus on the final product of achieving a mortal state. The followers of Plumbum, on the other hand, seek to understand both aspects of that transformation, firmly believing a Created cannot achieve their New Dawn until they fully understand and are comfortable with their Promethean existence.
