Biography
Kragnok was a sadistic jailer who was in charge of a prisoner named Pierre. He purchased a book detailing alien civilizations that existed below the Earth's surface. He sent Pierre to go digging for such a culture. Pierre succeeded in borrowing far enough into the earth that he discovered a race of bald albino underdwellers who welcomed him. With Pierre gone, the frustrated Kragnok spent the rest of his life trying to find another digger who was just as effective as his prisoner.
