The 13 Masters of Evil
The local priest of Yellowtail, running a temple to Thorax.
He was trained at the Temple of the Gods.
He assisted the party with deciphering the Dark Son activity in the Ruins of Cilox, and helped connect them with the Red Onyx Monastery.
From the information left at the Ruins, he advised the party that the Dark Son cult seems connected to the Elven kingdom in some fashion. He also said that the demon Viel seems to be the descendant of the queen of the elves, Lady Arabella. If this is true, it would mean that the Lady Arabella is thousands of years old; older than the First Great War.
