Grahmesh was a mighty warrior of the Fire Giants, he wielded a magical hammer that was forged from the very core of their King Kaomi a Titan among Fire Giants. It was said this hammer was the dying gift of the old Titan before his flame was extinguished deep below Kaomora. With one fiery lash of his hammer Grahmesh could forge hills and the mightiest of swings could raise mountains.
Grahmesh has all but defeated the ice giants when the titan of Peace Leventus broke the stone giants away from the land. This act created a great Tsunami that extinguished the hammer even if just for a few days, it was all the ice giants needed to mount a devastating offensive forcing a number of the fire giants to the north where their bodies said to form the obsidian peaks found in the ocean of that region.
Some say Grahmesh was taken captive and his hammer is locked in the shifting vaults deep within the Kurioso Depths others believe he was slain and now rests with the other fallen fire giants in the Obsidian sea. No one truly seems to know.
