Rokmar the Crackler

Following Draenor's destruction, Rokmar fled into the depths of Zangarmarsh. The energies that had torn the world apart enveloped the behemoth, bolstering its strength and size at the price of constant agony. The naga were awed by Rokmar's ferocity when they first arrived in the region. Rather than kill the beast, they enslaved it and used the creature to subjugate much of Zangarmarsh's indigenous life.
