From the introduction: “Beyond the sky, the world ash stretches from Hell to Heaven, supporting countless worlds besides our own. Between these strange realms, divine powers and the wild fight a war to control and define the whole of Existence, one idea at a time... or to unmake it altogether. The Nobilis stand in the front lines of this celestial struggle. Once they were mortal. Now they are something more. Each infused with a piece of Creation's power and given mastery over one part of reality. Love, War, Music, Steel, Thunder, Agony or any of Infinity's components: A Noble is its incarnation, master and protector.” - Nobilis: The Great White Book
