‘In the depths, pacts are made, and power is claimed. I am the voice of the sea's ancient might.’
— Tryphosa, Mother of the Sharks
The charming nereid witch Tryphosa, known as the Mother of Sharks, is an entity often engaged in forging pacts, much like the deal-makers daemons. Tryphosa is the one who secured the alliance of the Tidal Sharks with King Osteras's Mirmidons, sealing an ancient pact. She herself is part shark, hinting at a mysterious past intertwined with them. It is unclear whether her alliance with King Osteras’s Jurakin is temporary or what lies behind her suspicious machinations.
