The King Black Dragon (named Shakorexis by Hannibus) is an enormous, three-headed black dragon. He was the second dragon ever, created by Kerapac's fellow dragonkin Phalaks, a failed project intended to replicate the powerful Queen Black Dragon some time in or before the First Age. One decade later, he was released into the Wilderness. #himmelace #runescape
Killing the King Black Dragon at least once is one of the requirements of redeeming the Dragonkin lamp from Mr. Mordaut.
