Tron, Marvel, Star Wars, and Transformers are big enough to hold their own topics. They have movies, comics, and books written about them.
The Wings of Fire is just a book series. If there were Wings of Fire movies, then we could probably make a topic about it.
Though, I HIGHLY doubt people will make a WOF movie. The Wings of Fire stuff can easily fit into the What Book are you reading? Topic.
Not convinced by my argument? Ask @Hanna_Brassheart. She'll tell you that a topic about a book series is spam.
There was a James Riley(Author) topic and a Wingfeather Saga(Book series) topic. Both were closed.
WOF just isn't big enough for its own topic.
Heeeeeey, @Jacoby_Elderfun1! So nice to see you back!
