We don't choose our hyperfixations. They choose us!!!
looking at characters you loved from a past hyperfixation feels like staring longingly at an old friend you haven’t seen in years but miss dearly
my moots' hyperfixations are my hyperfixations-in-law btw
I call this dual-wielding interests
10 random facts about any of your hyperfixations go
TIME FOR YOUNG WIZARDS FACTS, YALL
We partly modeled our Code of Conduct after the Wizard's Oath which all preliminary wizards must swear before becoming a wizard. It varies somewhat from wizard to wizard and species to species, so we view our Code of Conduct as our nonwizardly Wizard's Oath.
In the YW universe, baaaaasically all myths are true, or have some degree of truth in them. This includes some of the Powers That Be having been several different gods across different cultures. Also they're not distant. Some take a quite active role in the world though the starring role definitely goes to the titular young wizards.
Wizards' pets typically get strange due to magic leakage and being able to be talked with by their wizards. Ponch, teen wizard Kit's dog, is definitely no exception. Later in the series he evinces a talent for finding lost things across different universes. When he does this, he always first travels to a pocket universe that is basically doggy heaven (for a certain kind of dog.) It contains an endless supply of trees and squirrels to chase up aforementioned trees.
There are alien wizards who are super cool. And alien cable, somewhat less cool. "A billion channels and nothing on," Kit's dad said, horrified.
Especially the cooking channels which sometimes feature humans, and not as the cooks.
One of the coolest characters (in our opinion) is not a wizard, just the big sister to one, who learns the magic language called The Speech and uses it to wreak positive chaos everywhere she goes. She once torments some "unfriendly" aliens who had been shooting at the main characters, with a bar of expensive chocolate which is a priceless collectible and intense drug to many aliens. If you don't cooperate, she tells them, "I'm going to unwrap it. And eat. It. ALL." Horrified at this prospect, they cooperate. Everyone deserves a big sister like Carmela.
Unlike most book series like this, the parents know and are supportive. Though the first reveal to Nita's parents goes a little explosive as her dad tries to forbid her from doing a dangerous magic that'll stop Bad Stuff from happening in the ocean but if she pulls out then millions - not just sea creatures, but millions of humans - will die. She stands on a chair and yells in his face, "Don't you get it? Some things are more important than doing what you tell me!" This is probably one of the top most cathartic moments for us in the whole series. He relents. Wizard kids take the parents to the moon.
There's so many easter eggs. My favorite is the tiny nod to The Fifth Doctor (I think that's the number) who helps one of the wizards by doing a fabulous impression of being falling down drunk, slowing down her pursuers and causing havoc.
Everything is earned. I cannot express this strongly enough. Also even in the darkest of moments there's hope, courage, and strength.
Diane Duane deserves to be a million times more popular than JKTERFling.
