Triton, a Scion of Poseidon (not that Triton) returned home from his first journey as the captain of his own merchant vessel… only he returned without his vessel (at least, without most of it). Never one to stand for bad luck to hold him down, he made his way to a local, reputable establishment known as the Last Barnacle and made the acquaintance of a mysterious elderly merchant named Psarion.
Psarion offered Triton an impressive sum to assemble a team of explorers and lead an expedition to an uninhabited island deep in the Mediterranean to retrieve a lost torc. Triton agreed immediately, asking minimal questions, and quickly gathered his childhood friends (oh God, how did htey lose their character sheets already?), both of whom are experienced warriors.
