From beyond, they come. They are spawned of That Which Is Not, and they hunger for That Which Is. There are a thousand-thousand blasphemies reflected into the gaze of the Abyss, and a thousand-thousand more beyond sight. One by one, slithering in secret, they crawl into the world. The day will come when the Awakened look up from their tomes and ruins and petty factionalism, and wonder where all the light in the world has gone. But it will be too late, then. --Govannon, Guardian of the Veil, archivist of Abyssal manifestations
