Flying was not an unfamiliar experience for Dorothy, but flying on her own wings was indeed a first in her life.
She had been somewhat worried that she might mess up since she had never used wings before, but once she actually tried it, she realized there was no need to worry about those issues at all. For the Dragon Witch, knowing how to fly with dragon wings was instinctual, just like one does not need to learn how to control their hands.
As long as the idea of how she wanted to fly formed in her mind, she could leave the rest to her instincts, and the dragon wings on her back would automatically adjust their posture, making everything fluid and natural.
This sense of freedom in flight was incomparable to her previous experiences flying on a broom, it was a joy unique to winged species.
