The Rock Lord is the name given to the semi-legendary Gargoyle who escaped when its master was killed in a Tzimisce attack. It began to live deep in the Carpathian Mountains, where it bred its own brood of independent childer.
The Tremere wonder about the identity of this "Rock Lord", and many believe it to be Chaundice, the first Gargoyle ever created. However, it should be noted that one named Ferox is also called "Rock Lord" by his fellows Gargoyles.
