Who Will Awaken King Matjaž?

Legend has it that a rich and just king once ruled Slovenia. When the Turks invaded from the east, Matjaž and his army fought bravely, but the soldiers fell one by one until only a handful of men remained by the king's side. When the king realized the Turks were too powerful, he fled with his army, and because he was a just ruler, he was not killed—instead, the mountain opened before him and took him inside. There he now sleeps at a table with his soldiers, and when his beard wraps around the table nine times, the king will awaken and come to redeem his people.
