The Hydraxian Waterlords are servants of Duke Hydraxis and enemies of the fire elementals, particularly Ragnaros. To this end, the Hydraxian Waterlords would offer assistance to any worthy invaders of the Molten Core, former home to Ragnaros. They would offer their essence, allowing adventurers to reach the sanctum of Ragnaros himself. The Hydraxian Waterlords ultimately serve Neptulon, the elemental lord of water. Neptulon, along with the other elemental lords, once served as heralds of the old gods. Though they initially fought against the old gods, they were ultimately enslaved by the old gods and used as pawns in the war against the titans. Neptulon, along with the other elemental lords, were ultimately defeated. The Hydraxian Waterlords would offer support during the invasion of the Firelands to end Ragnaros' violent reign once and for all. When the Burning Legion returned, Neptulon, along with the other elemental lords, were summoned by the shamans to do battle against the Burning Legion, a battle they would ultimately win.
