- Ghamoo-Ra – When the Twilight's Hammer cult arrived, its followers roused and imprisoned one of the last peaceful creatures living in Elune's temple. The cult delighted in tormenting the giant turtle for years, flaying its mind and body until it succumbed to madness. Naming the beast Ghamoo-Ra, the cultists trained it to attack outsiders and defend the Old Gods' shrine.
- Lady Sarevess – The Twilight's Hammer granted Lady Sarevess her own private cove within Blackfathom Deeps, continuously sending her fresh sacrifices. The cultists hope that her rituals and research will result in magical protection that will allow them to worship the terrifying hydra at the deeps' core without fear of becoming his next meal.
- Gelihast – The Old Gods called, and Gelihast answered, forcing his way into Blackfathom Deeps and slaughtering nearly a dozen surprised Twilight's Hammer cultists with his twin swords. Impressed by his ferocity and brutality, the cult allowed him to stay, and he built his own shrine to offer sacrifices and receive blessings from the ominous presence in the temple ruins.
- Old Serra'kis – Many of the creatures swimming beneath the Moonshrine Ruins were killed for food after the Twilight's Hammer cult took up residence, but the largest thresher in the water proved to be uncatchable, and those who persisted in hunting it inevitably died in the attempt.
- Twilight Lord Kelris – When the cultists found a strange three-headed creature in the belly of Blackfathom Deeps, Twilight Lord Kelris was convinced the hydra was a herald of the Old Gods' return to Azeroth... and his ticket to immortality. Kelris personally supervises the growth of the monster, even feeding him his own subjects to satisfy his wild hunger.
- Aku'mai – Aku'mai, an ancient evil, carries within him a small measure of the Old Gods' power. This three-headed hydra is greatly feared for his mindless savagery and insatiable hunger for living flesh, but the Twilight's Hammer worships him as a divine sign that the Old Gods will soon return.
