So far in the series, a great deal of the interest has come from the mysteries inherent in the foreign characters at the school. Right now, this page is a good place to put theories about the origins of characters whose home plane is only hinted at. Here be spoilers!
- Expy: According to the author, the series is based on a Massive Multiplayer Crossover role-playing game created and played by her family, and the finished story contains non-public domain characters with the "serial-numbers filed off." Hints are given by the princess's visions, and built on at various points in the narrative. Who is an expy of precisely whom is still up in the air for a lot of characters.
- Sakura Suzuki seems to be the expy of a Magical Girl anime heroine. However, she has an abnormal antipathy for magic in Rachel's world, having difficulty even riding a magical broom.
- Mr. Chanson the gym teacher can run fast enough to leave sonic booms and shrug off being blasted through brick walls. He seems almost certain to be Superman. Rachel even thinks of him as mild-mannered when she first sees him!
- Vladimir Von Dread is a college-aged Victor Von Doom, naturally.
- The princess' vision shows Valerie Hunt (Valerie Foxx in the first edition) as being in her early thirties, holding an important post at a major news coporation. Lois Lane perhaps?
- A closer look at the character and her father suggest (confirmed by Word of God) she is Veronica Mars; her father Kenneth Hunt is Keith Mars; her flirtatious friend Salome Iscariot and her dead friend Lilly Pfeiffer are both Lilly Kaine. The Princess’s vision of the date on Salome’s grave gives the correct dates for the events in this series.
- Kitten Fabian has clear memories of E. Nesbit's The Phoenix and the Carpet as one of the main characters (“Pussy” in the the Nesbit books; the Raven explains the name change as avoiding the unfortunate implications of that name in today’s world). Notably, she is also the owner of the talking lion, which provides evidence for her being from a world with Christianity.
- Word of God hints she might be Lucy from The Chronicles of Narnia....which is also supported by her talking lion familiar.
- The vision of Joshua March showed him being crucified and disemboweled on a glacier, and watched by a demonic figure who called himself Lightbringer. Note that he was one of the two students the Princess was warned not to touch, to protect her from this particular vision (the other being Von Dread).
- Gaius comes from a Sci-fi universe. His vision showed a moon-like space station being blown up - probably Star Wars, though none of the other details quite fit that world.
- Gaius Valiant was based on Gaius Baltar. In Book 3, someone who remembers calls him "The man who doomed the Galactic Federation."
- Seymour Almeida was seen fighting a magical duel in a glass forest, with a man in blue and silver armor. A spell wound gave that version of him the cheek scar.
- Magdalene may be a version of Vasilissa the Beautiful, between the abusive upbringing and the helpful doll.
- Book 3 reveals that she is actually a lamia, while her doll is a fetch.
- Nastasia may be descended from a Prince of Amber, hinted at by her power to have visions of other worlds, and Idunn's confirming that she could physically travel between them after completing a ritual.
- Zoe Forrest was based on Ramona Flowers.
- Valerie Hunt(a.k.a Valerie Foxx in the older versions) was Veronica Mars.
- Salome Iscariot was Lilly Kane.
- William Locke was William Bell from Fringe.
- The P.E. teacher Roland Chanson was Clark Kent.
- The Romanovs were the distant descendants of Corwin of Amber.
- Agent James Darling is based on grown up Harry Potter...if Harry had had the personality of James Potter, Harry's father.
- Scarlett Mallory Mac Dannan was originally Hermione. (Her husband, Finn Mac Dannan, was a character from another story made up by the same authoress. There is no equivalent to Ron in the story.)
- Illondria is probably Galadriel.
