The background design of Camus in this fanfic-for instance, that he was born into a noble family and was Saga's second-in-command-refers to Chinese astrological theories, which are also shared by Japan. According to the same theory, the sign of Cancer is associated with the underworld, which differs from Western astrology and Greek mythology. As an illustration, the Chinese astrology book "The Complete Collection of Astrology" states that "the Yuchi star in Aquarius represents intelligence and wisdom, and will strive in the north." Thus, this is highly compatible with Camus's background design, given that most Aquarius knights-including Hyoga-train and hone their skills in the far north of the planet. Furthermore, Aquarius Knights in LC and DW are also good at strategies. They represent intelligence and wisdom, which is what the book says,it also mentions that another star in Aquarius represents aristocratic birth and power,that's why in my work Camus came from a upper class background
