Duedor Cailean is the son of Lanliss Dexuma, a drunken man who abused his family, and Tessara, a quiet woman who only wanted to protect her son. The family lived in Sandpoint, where Lanliss often spent his nights at the bar. Tessara would often worry about him, and would go and bring him home. One night, Tessara left to find Lanliss passed out behind the bar, when a horde of goblins attacked the city. Both Tessara and Lanliss were among the casualties, leaving a 9 year old Duedor as an Orphan. Duedor was sent to an orphanage run by the church of Cayden Cailean, and stayed there for 30 years. Duedor often acted as an older brother to the new children, who would grow up and leave as Duedor remained young.
At the age of 40, Duedor left the orphanage and traveled to a place where he would feel more accepted, Kyonin. Duedor took his father’s last name, Dexuma, for this part of his life, to remember how much he hated his father. Little is known about this part of his life. At the age of 78, Duedor left Kyonin for a new experience, Absalom.
Duedor arrived in Absalom late one night, and found the first open bar and went inside. The barkeep was having a service to the god of ale and freedom, Cayden Cailean. Duedor was invited to join, and did. After the celebration, Duedor was about to leave to find an inn, when the barkeep offered to let Duedor stay with him. Duedor felt blessed, and decided to become a cleric of Cayden Cailean. Duedor was under the instruction of the barkeep, who also served as a priest. Duedor went out one night to explore the city, and when he returned, he found the barkeep had been robbed and murdered by a corrupt tax collector, and worshiper of Asmodeus. Duedor took the longsword from the bar and went tracked down the tax collector and murdered him.
Duedor realized that night that his duty was to Cayden Cailean, but not in the form of a gentle cleric, or a kind barkeep, but as a vengeful inquisitor, who would travel the world to protect all worshipers of Cayden Cailean, and all good people from evil. Duedor then took the last name Cailean, as many orphans do, as a sign of his devotion.
Duedor Joined the Pathfinder Society as a way to easily move around, and to give him more resources for his duty.
