Burial Mound of Esur the Red

In order to defeat a great evil that haunts the land, or to fend off invading armies, or a similar task of heroes, the characters have to find the Ring of Esur the Red. 

Esur the Red was a powerful fighter, a noble son of a ducal family of the kingdom who went on to also become a great noble of the northern barbarian tribes. After his death, it is said that eight hundred of his tribesmen marched to the city gates demanding his body so they may bury it with the proper rites due his rank. 

Of his legends, one item repeats in them all – the heavy black iron ring that he held his braided beard clasped in when walking into battle. With this ring, he is said to command the waves of any body of water within sight.
