Thassa
God of the Sea Thassa
The Present
In the modern era, post-Nyx, mortals turn their view of the sea into nothing more than a relentless and unforgiving terrain, which is mastered by few.
The Past
Thassa is the god of the sea, aquatic creatures, and the unknown depths. She also holds sway over less tangible concepts such as ancient knowledge, long voyages, and gradual change.
Impassive and slow to anger, Thassa is secure in the knowledge that there are no mortals and few gods who can threaten her status. Once her ire is aroused, however, it is as unstoppable as a cresting wave. She often speaks in the future tense, referring to what tomorrow will bring. She seldom laughs, and when she does, it is usually out of smugness rather than genuine mirth.
To most mortals, Thassa is the sea, and the sea is Thassa. The wind and waves, the tides, and the ocean's bounty, ranging from small fish to the enormous krakens—all these are Thassa's dominion.
Krakens and other behemoths of the deepest oceans move at Thassa's command. She is protective of what she calls the greatest of her children, and she usually keeps them out of harm's way in the darkest depths. A mighty kraken sighted close to shore is a sure sign of Thassa's displeasure.
Divine Domains
The sea has many metaphorical aspects that Thassa oversees as well: ancient knowledge, long-term change, introspection, voyaging, and repetitive patterns such as the tides.
Thassa governs the slow changes wrought by the passage of time, such as the weathering of rocks and the erosion of beaches. Where Nylea controls the eternal cycle of the seasons and Kruphix monitors the flow of time, Thassa holds sway over the slow-acting but irresistible forces that alter the world over hundreds or thousands of years.
Tenets of Faith
Most of Thassa's dedicated worshipers are tritons, and the vast majority of tritons are wholly devoted to Thassa. Tritons spend much of their lives in Thassa's realm, with their god omnipresent. They weave prayers to Thassa into nearly everything they do.
Among humans, Thassa is worshiped by those who rely on bountiful seas for sustenance or calm waters for safety. Sailors, fishers, and residents of Theros's coasts and islands all pay her at least nominal respect and sacrifice. Her center of worship on land is in the coastal polis of Meletis, where sailors and philosophers pray to her for guidance. The week-long Lyokymion festival (the Feast of the Melting Swell) marks the start of the new year by celebrating the bounty of the sea.
Thassa's most fervent human worshipers offer prayers at high and low tide. If possible, they do so at the water's edge. At low tide they walk barefoot out onto the tidal flats, relishing the touch of Thassa's seabed.
