“"The Starkrial Valley was once lush and hearty. But the ogres dammed the river and let everything wither on the southern end. The lake that remains is red and acidic. Many things that touch its surface do not survive."”
—Mitya, in Book 4: Neverseen
The Lake of Blood is a lake located in Starkrial Valley. It lies in the Neutral Territories. In Neverseen, Lady Gisela was seen dragged near it by members of the Neverseen. She was seriously injured by the shamkniv. They dragged her into a cave on one of the sides of the valley, later discovered to be an ogre prison.
