Cherlrigo's Darkness was supposedly the translation (by Cherlrigo) of a sonnet that could be found within The Leaves of One Grass, a work of prophetic yet cryptic messages penned by the Dark Diviners of Windsong Tower in Myth Drannor. This particular passage was thought to have originally been written two thousand years before the mid-fifteenth century Dale Reckoning and was heralded by many Shadovar nobles and sages, including Draygo Quick, Parise Ulfbinder and Rolan of Gloomwrought to directly relate to the power of the Shadowfell and have something to do with the Chosen.
