In-game description: "The Grandfather River flows through the Empire, taking with it a tale of years too long for human memory. Sailors of merchant vessels on the river speak of the ghost of a woman crying out in agony. She has been named the Grandfather's Daughter. Only once has she come ashore, and legends say she left behind a single tear in the form of a gem. Every single owner of that gem, as the legends go, has felt her pain and sorrow throughout his life, his body wracked by pain but his mind and spirit made sharper by clarity."
