Worldbreaker, the Hammer of Unyielding Might

This enormous warhammer has a head of dark star-metal banded with veins of golden stone. Each face bears a different rune representing force, endurance, dominance, and unbreakable will. Its haft is wrapped in petrified giant-hide, yet the weapon feels perfectly balanced in the hands of a worthy wielder. When raised, nearby stones tremble and the air presses outward as though the world itself is bracing for impact.
