Sthenno is immortal and cannot die from natural causes. She is not subject to death from massive damage and is immune to death effects and disintegration. She does not age, and does not need to sleep, eat, or breathe.
Though the word gorgon is often associated with the deadly bull-like creature that turns a victim to stone with its breath weapon, the true gorgons are three sisters; Euryale, Sthenno, and Medusa. They are the daughters of the god Phorcys and the goddess Ceto. Euryale and Sthenno were born immortal and are hideous creatures with writing snakes for hair, brass claws, wings, and a gaze that can turn any living creature into stone. Phorcys tasked them with guarding the entrance to the Underworld.
Medusa was born mortal and was very beautiful. Phorcys sent her to the Material Plane so all could gaze upon the beauty of his daughter. Medusa’s beauty rivaled that of some of the goddesses, and some of them grew jealous of Medusa, particularly the goddess Athena. Her beauty also turned the heads of some of the gods, and when Poseidon seduced her in a temple to Athena, the goddess became enraged and changed the beautiful Medusa into a creature as hideous as her sisters. Poseidon turned from his love, never to return again. Medusa, enraged, fled into the desert and never came back to civilization.
The hero Perseus was tasked with killing the gorgon known as Medusa and bringing her head to King Polydectes as a wedding present. Using a magic shield given to him by the gods, he avoided Medusa’s deadly gaze and severed her head. From her serpentine body sprang the children of Poseidon, creatures similar in appearance to their mother. These creatures escaped into the world and are called medusa.
Sthenno and Euryale long for their sister’s return or their meeting with her in the Underworld. Yet being immortal, they cannot enter the Realm of the Dead. Thus, both know they will never see their beloved sibling again. Their cries are said to be audible on the wind as a high-pitched shrill akin to a bird’s cry.
Both Sthenno and Euryale are 10 feet tall and weigh around 600 pounds or more. Sthenno’s eyes are blue; Euryale’s eyes are copper.
Sthenno and Euryale rarely enter combat unless pressed or provoked. They are both deadly combatants and use their claws, bite, snakes, and petrifying gaze with precision force. Sthenno enjoys “collecting” those she has turned to stone and even has a room in her lair where she displays them. Euryale simply smashes to rubble those she has petrified.
