Boreus was a member of The Four Winds before they split around 20 years ago. He was known as somewhat of a party animal.
It recently came to light that he is behind the missing wine shipments in Mytros, having set-up shop in a glade in the Agricoles to 'help' a Nymph called Ashe take revenge on a family she feels has broken an oath to her. This family are actually Trellus and Septia; and the Oracle's Chosen have given a tentative 'maybe' to helping him. He has Kyrah's harp, and has agreed to give this to the group if they assist.
