Shards of Alexander
Light and Darkness
The Light is regarded by the Virtuous as the manifestation of Altana’s power and literally the stuff that all matter in the universe is made of. Colloquially “The Light” can also refer to the will of Altana or the Eidolons. The Light (capital L) is thought of as being different from the light (lowercase l), where the former is an element of the divine, the latter is a natural effect. Because of this, The Light need not appear as rays of light and so it can appear as something entirely different. Indeed, the Crystals of Light are literally crystallized pure light.
The Darkness is considered to be something completely different. The origins of The Darkness is unknown, though the Verethragna describes it as being present at the beginning of time. Unlike The Light, which is understood to be an elemental expression of Altana, The Darkness is sentient corruption. It has it’s own will, drive, and purpose, though the exact nature of these are unknown. In large concentrations, it can manifest as creatures and monsters of frightening power, but it can also possess the weak of will, corrupting their minds and forcing them work against the light. This process is known as tempering, and is irreversible.
For hundreds of generations, The Darkness has chased and attacked Alexander and its crew.
