Everyone knows that Wizard101 constantly makes references to other pieces of media (played to the extreme with Empyrea), but there's one in the Catacombs that I'm surprised more people aren't mentioning: Professor Hargrove.
Hargrove is most likely an obscure cameo of the artist Gregg Hargrove. For those who don't know, he illustrated a lot of the early concept art and textures for Story Arc 1, mainly the spell art, most NPCs, and the loading screen with the Pyromancer (Simeon Firemane) and the Thaumaturge (unnamed). You can see him in the credits near the bottom if you wait half an hour (it would be cool to see separate credits for separate world expansions, but whatever). The genius behind the cameo is that, in-story, he is exploring the old ruins of early Wizard City inhabitants, and in real life, he created early Wizard City artwork.
Anyway, he has a website, of course, which houses some of the concept art he worked on (some of the art from other games, like Dimentium, are graphic for some, so visit at your own risk for those). There are many interesting concepts that went unused under his Wizard101 section, such as the infamous Ambrose/Greyrose role swapping, Gobblers having a ghost variant, etc., but the one I want to discuss is Cyrus' name... he is called "The Professor of Order" in his artwork.
In other words, the School of Myth was originally going to be called the School of Order.
This explains quite a few things. The symbol for Myth is also the symbol for the New World "Order", which is self-explanatory, but Order also explains why Cyrus is bossy and disciplinary: he literally "orders" his students around.
But the real genius is how this ties into Pigswick Academy.
The Pigswick schools of magic have similar names to their Ravenwood counterparts, but have completely opposite philosophies (Frost Magic, for instance, is fragile and weak until it crystallizes, as opposed to Ice's philosophy of slow, unbreakable glaciers). The School of Chaos doesn't sound like it has any correlation with the word "Myth", but it does tie into "Order". "Chaos" is the polar opposite of the word "Order", and one would only get the reference if they knew Myth was called that to begin with.
Anyway, yeah, I wanted to point these two references out.
