Iris Selwyn, the sharpest tongue in Slytherin and Hogwarts' one-of-a-kind Quidditch commentator.
She adored the open sky but had no talent for flying, so she couldn't take the Quidditch pitch. All she could do was stand on the commentary platform and live out her dream of flight through the rises and falls of others.
A pawn in the Selwyn family's marriage alliance, she watched Sirius Black, who had been born with everything, with a mixture of envy and resentment.
On the train, she publicly denounced her nominal fiance, exposing the sham behind their respectable engagement. At the Christmas family gathering, Sirius decisively broke off the engagement, severing the ties between their families.
No one knew she'd already refused to be married off to Regulus. No one remembered that the rebellious Black had once placed the golden snitch he'd won into her palm with his own hands.
She'd once thought that even if they were unfeeling, at least they understood each other.
Later, a black-haired boy with glasses and unruly curls came swooping down on a broomstick and asked her, "Do you want to fly?"
The girl trapped by fate would one day break free of her shackles and live for herself.
Theme: A girl never has to wait for someone else to save her. Girls can lift each other up and heal each other, holding on to one another in the mud. Or they can become their own knights, depending on no one's light, standing tall and brave on their own.
