Some fans and licensed book authors theorize Wraith names are telepathic, representing the mind feel of the individuals, even multi-layered and multi-sensory.
In “The Hive,” the Queen asks John, “Of which Queen do you speak?”
What should John have called the other Queen? The green one with the long hair? 😛 Are the true worshippers given names or, at least, name approximations? What is written in ship logs (or, if ships can record telepathic data, what gets written elsewhere)?
Different Fandemonium books had different naming conventions and cultures: the Legacy series with mindfeel names and the Eidolon in Entanglement with sci-fi sounding names that may or may not mean anything.
As far as I am concerned, this all leaves the door wide open for fan canon. Have fun with it!
