He was Fiona’s lover and later her husband. He wrote almost everything about the war between Poseidonians, led by Orin and Bazil, and Tritonians, led by Dardanus and Kordax.
During the battle for Atlantis, Kordax attacked Regin and was about to kill him, but Fiona appeared and defeated his older half-brother. He also witnessed the fight of Orin against Dardanus and the spirit of Shalako. His interpretation about that fight was always doubted by his wife, Queen Fiona, who tried to find a logical explanation, ruling out the presence of spirits.
The last mayor episode he wrote was Kordax’s punishment (the loss of his left arm and banishment), under the orders of Queen Cora.
