Octantic is a term describing someone who is not only devoid of sex, gender, and orientation but also removed from those concepts entirely. It's the combination of apogender, panaspec (or apoattractional), and angenital (or apogenital/aposex).
Flag
The flag uses the symbol of Octans to convey a sense of remoteness, as Octans contains the southern pole star, and octants are used for navigation. The symbol also looks like an “A” for “apo-”.[1]
