Thalassa is the planet sixth closest to the star Atos, and the second - and largest - of the system's four gas giants. It is also, furthermore, characterized by its distinct golden rings. After Azos and Tarsica, Thalassa is the most prominent body in the Micrasian night sky.

North Polar Regions

The North Polar region of Thalassa is characterized by its tranquil yet icy atmosphere. Unlike the turbulent poles of many gas giants, Thalassa's North Pole is relatively calm, featuring slow-moving cloud formations composed mainly of methane and ammonia ices. The temperature in this region is exceedingly low, resulting in a serene, almost otherworldly landscape dominated by shimmering ice clouds. This calmness allows for a more stable and clear view of the polar region, with fewer storms and atmospheric disturbances. Occasional auroras, caused by the interaction of Thalassa's magnetic field with solar winds, add a mesmerizing touch to the polar skies.

Equatorial Regions

Thalassa's Equatorial region is a stark contrast to its poles, marked by vibrant bands of blue and white clouds. The equator is the warmest part of the planet, receiving the most direct sunlight. This region experiences dynamic weather patterns, including massive thunderstorms and high-speed jet streams. The blue coloration is due to the scattering of sunlight by methane in the upper atmosphere. The presence of fast-moving jet streams creates sharply defined bands and contributes to the planet's visually stunning appearance.

Southern Polar Regions

The South Polar region of Thalassa is a mix of calm and chaotic elements. This region features a combination of smooth, icy clouds and sporadic storm activity. The South Pole is slightly warmer than the North Pole, allowing for the formation of larger and more complex cloud structures. This region is known for its unique polar hexagon, a six-sided jet stream that encircles the pole, creating a geometric cloud pattern. The hexagon's stability and persistence are subjects of scientific fascination, as it remains a mysterious and distinctive feature of Thalassa. The interplay between the hexagon and surrounding storm systems results in a captivating and dynamic polar environment.

Golden Rings

Thalassa's vibrant golden rings are a captivating feature of this gas giant, distinguished by their striking color and intricate structure. These rings are primarily composed of ice particles mixed with silicate dust and organic compounds, which reflect sunlight in a way that creates their characteristic golden hue. The particles range in size from tiny micrometers to larger chunks, and their composition is influenced by Thalassa's proximity to the star Atos. The rings' golden coloration is likely due to the presence of tholins, complex organic molecules formed through the irradiation of simple hydrocarbons by ultraviolet light. These tholins absorb blue and ultraviolet light, scattering the longer wavelengths that appear golden to human eyes. The rings are kept in place by the gravitational influence of Thalassa’s numerous moons, which shepherd and maintain the ring's defined edges through their orbital resonances. This delicate balance between the moons' gravitational forces and the centrifugal forces of the ring particles creates a dynamic and ever-changing but stable ring system that is as scientifically intriguing as it is visually stunning.

Moons

In 49.84 PSSC, Bassaridian researchers confirmed the discovery of ten additional, lesser moons in orbit around Thalassa. Information regarding these newly discovered moons can be found in the table below

Mythology

Origin

Thalassa, the Lady Divine of the Sea and War, emerged from the depths of the ocean. Born from the tears shed by Atos when the sun was tortured for stealing the light of Azos, she embodies the mysteries of the ocean's depths and the fierceness of its storms.

Epithets

Thalassa is adorned with epithets that reflect her divine nature and influence. Among these titles are "Mistress of the Deep," symbolizing her dominion over the unfathomable depths of the sea, and "Sovereign of Storms," representing her control over the forces of nature. She is also known simply as the "Empress," signifying her exalted status among the pantheon of Reformed Bassarid gods and goddesses.

Worship and Festivals in Bassaridia Vaeringheim

Members of the Azure Sentinel Sect congregate at a small coastal shrine in order to pay honor to the goddess of the sea, and the queen of the Planetary Divines.

In the coastal cities and port towns of Bassaridia Vaeringheim, especially in the nation's capital city of Vaeringheim, worshipers of Thalassa gather to pay homage to their divine patron during rituals and festivals which take place throughout the course of the year, the most famous of which is the The Rite of the Tidal Communion. This sacred ritual takes place during the changing of the tides, when the ocean's power is at its peak and the connection between Thalassa and her followers is believed to be strongest. During the ritual, members of the Azure Sentinel Sect gather at a secluded coastal shrine dedicated to Thalassa, situated upon a rocky promontory overlooking Lake Morovia. As the lake's waves crash against the rugged cliffs below, initiates prepare themselves for the ritual by donning ceremonial robes adorned with symbols of the ocean and war. The ceremony begins with a solemn procession led by the sect's highest-ranking priestesses, carrying offerings of seashells, pearls, and other treasures to lay at the feet of Thalassa's shrine. Participants then form a circle around the shrine, facing towards the sea, and begin chanting ancient hymns invoking Thalassa's blessings. As the tide begins to rise, reaching its zenith, the participants enter into a meditative trance, induced by extremely high quantities of Noctic-Rabrev, wine, and psychedelic herbs, allowing themselves to become attuned to the rhythmic pulse of the lake's power. They open themselves to Thalassa's presence, seeking guidance, protection, and strength in their sacred duty as guardians of the waters. During the climax of the ritual, participants extend their hands out towards the sea, offering up prayers and invocations to Thalassa. They beseech her to grant them the wisdom to navigate the treacherous waters of life, and the courage to face any challenges that may arise.

Azure Sentinel Sect

At the heart of Thalassa's worship lies the esteemed Azure Sentinel Sect, a sacred order dedicated to the protection of Lake Morovia and the Strait of Haifa, and the preservation of ancient Bassaridian maritime traditions. Comprised of skilled sailors, courageous warriors, and highly devoted mystics, the sect operates as guardians of the coastal realms, defending against threats both natural and supernatural. Members of the sect are known for their mastery of seamanship and maritime magic, harnessing the elemental forces of water and wind to safeguard the ocean's bounty.

Mythology

Ancient myths and legends depict Thalassa as a figure of awe and reverence, her origins steeped in mystery and ancient lore. She is often portrayed as a powerful and enigmatic deity, capable of both nurturing life and unleashing absolute, unparalleled destruction with the fury of the ocean's wrath. Tales of Thalassa's exploits in battle against monstrous sea creatures and rival deities are recounted with reverence and awe, inspiring both fear and admiration among mortals. Thalassa is regarded and revered as the uncontested most powerful of all Planetary Divines.

Iconography and Depictions

In art and iconography, Thalassa is often depicted as a regal figure adorned in flowing robes of azure, her form wreathed in swirling mists and crashing waves. She is frequently portrayed holding a trident, symbolizing her mastery over the seas and her authority as the Lady Divine of War. She is typically depicted with her eyes closed, reflecting the belief that her gaze is capable of driving man and beast alike into the frenzy of war. Symbols associated with Thalassa include the conch, representing the depths of her domain, and the Atteran River Shark, symbolizing her formidable, fierce power and the mysteries of the deep. Depictions of Thalassa capture her majestic presence, inviting worshipers to contemplate the vastness and beauty of the maritime realm.
