I don't think she'll pick up a Knight form later.
What she got out of fairy tales is apparently that the Princess gets to have all the things and the Dragon gets to light people on fire and take all the things.
Two great flavors that go perfectly well together in Haneyl's imperialistic mind.
Well, perhaps more pertinently a knight is just a human wearing armour, and as a princess she's not at all prepared to be told she can't have armour. She's going to have the best, most expensive armour that's far better than anyone else's armour. It's going to be made of orichalcum and covered in flowers and emeralds and you'll be able to see her glowing green eyes through the visor and...
Vali: "Yeah! And if anyone threatens her and she doesn't deserve it, I'll smash their face in."
Haneyl: "Wonderful! You need armour too! My little brother has to be the best little brother-knight! And provide all the masculinity that Rathan is lacking!"
Rathan: "I will have you know that my armour is prettier than yours, and when I take my helmet off women and men go weak at the knees as my mass of hair comes spilling out and I bishie sparkle. If that's not masculinity, what is?"
Zanara: "I have armour too!"
Vali: "Zanara, your armour is a blasphemous and weirdly sexualised thing of coral, pearl and opals that looks like a living statue and men who look at it go mad and mutate into tentacle monsters."
Zanara: "... what's the problem?"
She already lives in a swamp and has green as her primary color motif. I think it's too late.
Not really. See, Haneyl's thing is basically that she's early modern absolutism and imperialism, meets Disney. So she's not going to make an ogre like Shrek - if she makes ogres, they'll be hulking knights she feeds raw meat to and sends out to crush people who don't pay taxes.
Basically, what happens if you merge the idea of a guard dog and a man at arms.
