While the Eidolon represents the force of order, offering a glimpse of an inherent organization of reality, the Umbra is its polar opposite, unpredictable and tumultuous, a chaotic, entropic force that destabilizes, mutates, corrupts, and disorganizes reality. All matter is caught between these two forces, affected by both to some degree, and their interplay is at the fundamental source of all great emanations of power.
