Age of Aventus
Thassa is the goddess of the sea and also presides over aquatic creatures and the secrets of the briny deep. But she is also the goddess of ancient knowledge, murmurs, gradual change, introspection, vast distances, long voyages, and far-ranging searches. Thassa might also be described as the goddess of patterns, such as those of tides, currents, ripples in water, and even the passage of time.
Thassa is the goddess who is least likely to be satisfied with the status quo, but also the least likely to rush to change. She is constantly striving to re-sculpt the land, changing coastlines and upending institutions for the purpose of slow, eventual, unfolding change.
When she speaks, she often uses the future tense, always referring to what tomorrow will bring, forever uninterested with the reality of today. Thassa is slow to anger but implacable once roused. Her anger can grow like a rumbling, cresting, unstoppable wave, taking out whole villages with its fury—then subside with the tide, dragging the evidence of her wrath calmly out to sea.
Tritons and the humans of Meletis comprise most of Thassa’s worshipers, as well as all who venture out to sea, whether for exploration, commerce, or war. Although tritons exalt her above all other gods, she shows no favoritism toward them, seeming equally impassive to all mortals. She is worshiped with offerings of fish and salt by the poor, offerings of pearls and nacre by the rich, and with murmured prayers and quiet contemplation by all.
Thassa wields Dekella, a two-pronged spear. Wielding Dekella allows her to control the tides and stir the seas into whirlpools. Legend has it that a mortal sailor once stole Dekella and used it to destroy an enemy fleet, and that Thassa punished the mortal by turning his entire family into eels.
