Callaphe

Callaphe was a human trickster from Meletis who sailed a ship called The Monsoon. Now she is Thassa's chosen demigod.

Age of Heroes
Callaphe was the most skilled mariner to ever sail the seas. She was also the first mortal to decipher the secret patterns of the winds (thus provoking Thassa’s ire), and she sailed over the edge of the world and into Nyx to claim her place among the stars. Her adventures are recounted in the epic poem known as The Callapheia.

Theros Beyond Death
When Heliod instructed his champion, Daxos, to remove all trace of the other gods from the city of Meletis, Thassa and the other gods, refusing to stand for such an affront, called upon their own champions from the Underworld and made them demigods.

In life, Callaphe has gained Thassa's respect by outmaneuvering her krakens, and because of that respect, Thassa chose Callaphe as her champion.

Inspiration
Callaphe's exploits mirror that of Odysseus, letting her encounter the Sirens (Cloaked Siren) and Polyphemus (Nyxborn Brute).

In contrast to Odysseus, however, Callaphe earned the respect and favor of the sea god.
