Origin
Thalassa is named after The Classical World Primordial goddess of The Sea or Primeval Spirit of The Sea, Thalassa. Thalassa was the daughter of Aether, The Primordial god of the upper sky, and Hemera, The Primordial goddess of the day. Thalassa siblings were Gaia, The Primal Mother Earth goddess, and Uranus, The Primordial god of the sky. Thalassa is known for spawning the storm gods or giants and The tribes of fish. Also Thalassa is the mother of Aphrodite, The goddess of Love, Beauty, Pleasure, passion and procreation, and Halia, a nymph who lived on the island of Rhodes. Thalassa and her husband Pontus, The Primordial Sea god, would one be replaced by new marine god couples, first being Oceanus and Tethys, Titan god and goddess of the sea, and then Poseidon and Amphitrite, Olympian god and goddess of the sea.
