The Watcher of the Mists
Black Magga is a legendary creature that supposedly lives in the great freshwater inland sea known as the Storval Deep, in Varisia. A gargantuan beast, she allegedly appears to be a cross between a sea serpent and a giant squid. She is supposed to possess a vast and terrible intellect, and has mystical powers that can bore into the minds of lesser beings to cause insanity and force them to do her will. According to the Book of Lamashtu, Black Magga was mentioned as one of the favored children of the demon-goddess, and is one of a family of creatures called the Mothers of Oblivion.
Black Magga was sighted on 8 Kuthona 4711 in the town of Turtleback Ferry, after the partial breach of the dam called Skull’s Crossing. The Sandpoint Heroes managed to chase her off before she could do too much additional damage to the flooded town.
