Sigurðr's massive sword Gram could slice through dragonhide with ease and his superhuman flesh was impervious to their fiery breath. The one dragon who served him, Grani, rarely met another who could match his strength. Also, the power granted to him by his divine father was enhanced by the bonds he had formed with fellow demigods.
