A furry in black clothing visits the grave of her mother, who was 1 of the 25 victims in which were murdered by a serpent snake named Seyox. His motive was that he was betrayed by his friends who blacklisted him for manipulation. In retaliation, he was cursed in courtesy of a Varrien witch and is now on the hunt for those who have wronged him.
