It is a short staff carved with mysterious runes, similar to those adorning the Black Sword. Duke Dorian Hawkmoon's great quests and campaigns were largely centered on gaining control of the Runestaff in order to defeat the Dark Empire of Granbretan.
"Those who dare swear by the Runestaff must then benefit or suffer from the consequences of the fixed pattern of destiny they have set in motion.
Several such oaths have been sworn... but none with such vast and terrible results as the mighty oath of vengeance sworn by Baron Maliadus... sworn in that year before Dorian Hawkmoon, that aspect of the Eternal Champion, entered into this ancient narrative".
