Once established in the Glittering Caves of Aglarond, Lord Gimli forged a bond of friendship with King Eomer of Rohan. A small company of horsemen patrolled the roads from the White Mountains to Erebor. In exchange, an elite group of Dwarves was lent to Meduseld. Taking on the Khuzdul word for grass, they became known as the Yerêg Guard. They were a visible presence anywhere Dwarven craftsmen did their great works of building in the horse-lord’s kingdom.
