The Blackrocks captured three members of Krol's clan and convinced them to hold council with their leader. Krol, promised protection from the gronn, as well as a new "enemy" called the draenei in which to kill, quickly agreed and formed an alliance with Blackhand. ( )
After the destruction of Draenor, the Boulderfists settled in Nagrand. Recently, Krol has gone mysteriously missing and a new clan, the Warmaul, have begun forcing his clan out of their lands. The cunning half-orc Lantresor of the Blade has stepped up and taken leadership of the clan. The Krol Blade may or may not be named after him.
