Krark was a legendary goblin on Mirrodin who travelled to the hollow center of the plane and catalogued his journeys in a book, which holds the fundamentals of the religion known as the Cult of Krark, which believes that Mirrodin is hollow, and its leader preaches from the Book of Krark. The Book of Krark states that if you look at the mana core, your eyes will turn to ashes and your feet will turn into goat hooves. Krark is believed by his cult to guide the souls of the dead to the Steel Mother. The Krark-Clan is named after him.
