Dubhlainn Ua Artigan, is the faerie king, a sole male in the whole faerie race that is married to the faerie queen Aibell. They live in the largest faerie mound, the Mound of the Hollow Light. Although all faeries obey him, Dubhlainn has no say in governing, or any of the faerie affair. His existence is limited to prolonging the life of faeries by mating with them. He has one daughter, Sleipial who will be the next faerie queen.

Dubhlainn's design is a homage to Oberon from Shin Megami Tensei. He is 168 cm tall and weighs 56 kg.
