I'm a big fan of the myth school, especially the Greek mythology references in it. One thing that's always bothered me though is that the myth symbol in the game is the Eye of Horus, a part of Egyptian mythology, but the game's Egyptian world Krokotopia is balance themed. As much as I love Greek mythology, I think Wizard101 should create a dungeon like Olympus where we can meet Egypt-inspired mythological beings like Horus. Maybe even Egypt-inspired spells could be a part of it? Getting to summon Horus himself would be amazing. I also love fire, so maybe the sun god Ra could make an appearance? Or Sekmet, she would be cool.
Ra can be fought as a wooden skeleton key boss in the Krokotopia library. Additionally, Ammit the Devourer mentions at the end of the House of Scales dungeon that Sekhmet will soon be coming for us, although this has not been "paid off" yet in the storyline.
