On the Isles of Santerra... The all female pirate crew, the Daughters of the Deep, are the only thing standing between the Saints of Santerra and their goal of slaughtering every siren in the sea. The rest of the Isles of Santerra believe in the mission of the Saints, but the Daughters know that the real monsters aren't the sirens, but the Saints who seek to slaughter them. The Daughters won't rest until the seas are safe from the Saints.
