Percy Jackson and the Olympians: Legends

Amphitrite was described to be a gorgeously beautiful woman, with black hair pinned back in a net of pearls and silk, a circlet of polished red crab claws across her brow, mocha-dark eyes, a kind smile, and a beautiful laugh. She also radiated a gentle kindness that particularly distinguished her from her sisters and other gods, and usually wore a simple white gown. Above all she is the loveliest and most beautiful of all the Nereids.

Amphitrite prefers to live a quiet life and enjoys her independence. Delphin noted that it was easy to see why Poseidon preferred Amphitrite to all her sisters, for she radiated a gentle kindness that was rare among goddesses. Amphitrite used to be shy and avoid courtships from male gods because of the intense fear she had conceived from hearing stories of how gods treat their wives, believing that being married would rob her of her freedom. She is perfectly content with her lot so long as it is reasonable: she knew Poseidon wouldn't be a faithful husband, but doesn't care about that due to not being prone to jealousy and is content as long as he doesn't try to turn her into his puppet and treats her children well.

Amphitrite is the Goddess of the Seas and Queen of the Sea through her marriage with Poseidon and one of the fifty Nereids. Along with her sisters, Amphitrite came to the aid of sailors in distress, fought perilous storms, and took care of the sea's rich bounty.
