It's safe to assume that all denizens, bar Yaldabaoth, are assigned based off of aspect. And I'm not really behind the gender part of the theory, partially because Calliope is implied to have had Yaldabaoth as her denizen as well as that Hephaestus and Nix would, going by the aspect theory, be assigned to both male and female players (Dave Strider with the Megidos and Roxy Lalonde with the Zahhaks, respectively).
