Grazak was told nothing of his mother's past until his older brother attacked her in a fury, demanding to know who his father was. She wept and told him where to look, but when Grak returned he was mad with terror and raving about fire. To protect his mother, Grazak took this bone from the corpse of a great beast and drove his brother away.
