[Well... this does give at least some clue to the hierarchy of... sentient books. Hermes thinks. Hermes is aware cultures can vary from species to species, such as how Soothals have a class-based system based on the shape of their heads, Gondii being parasites that mind-control organisms that aren't sentient, or how millions of Datos form a colony the size of a common beach ball.

It would be best to clarify this 100%. Just in case.]

Just so we're clear, do you mean "overlord" as in "A ruler of great power"? Or is there another definition your species uses?
