I guess I have to say that I am the most faithful to my life wizard. She is a level 31 now, (or was it 32?) and I guess she is my favorite because she was my first wizard. I would spend more time with my other wizards, but now that I know what else is out there, wizard city is just so ... boring...
My favorite school is definitely Fire. It matches my personality exactly and my favorite season is summer. My very first wizard, Blaze Shadowflame, is my highest level wizard and he is always the first to start a new a new world. I like Myth too but Fire will always be my favorite. 8)
