As mentioned before, Nadine had been a relatively thoughtless girl who didn't place very much of an importance on studying.
Not much at all...
So in that regard, it was relatively unsurprising that she didn't know a single lick of magic- and she didn't possess a vast wellspring of magical power either.
On the other hand, Cyrulle was a natural magical prodigy on account of her heritage.
For that reason, one was given substandard restrictions while the other was given much more stringent ones.
Cyrulle couldn't even move with all of the locks and barriers placed on her. She wouldn't be able to speak either if it weren't for her gift of telepathy.
As Nadine began to harbor more and more of a plan to escape, she consistently kept Cyrulle calm and told her not to panic.
Perhaps that was when the dragon started to take more of a liking to her.
