One of the most ancient King Anatinuses was possibly one of the early rulers of the Anatian Empire which stretched from the Mithicus Mountains to the eastern shores of Antharia before the founding of the Kingdom of Quendor. If so, this king was human, while his later ancestors would be platypuses following a magical mishap. The father of Anatinus was Aneas V, and his son was King Aneas VI.
