The first time you hear the phrase "price of blood", it’s whispered in the Slytherin corridor like a curse that hasn’t decided what shape to take yet.

You’re walking beside Lily Evans when it reaches your ears. She stiffens instantly, fingers tightening around the strap of her bag. Lily always hears things before they land - insults, rumors, danger. It’s a survival skill you’ve watched her sharpen since first year.

“Don’t,” you murmur, already knowing she’s about to turn back.

“I’m not afraid of them,” Lily says, chin lifting. Her green eyes are bright and furious. “And I won’t pretend I don’t hear it.”

That’s the thing about Lily Evans: she refuses to shrink, even when the castle seems built to remind her she’s other. Muggle-born. Mudblood. A girl who dares to be brilliant anyway.

During the war, brilliance is dangerous. Muggleborns and muggles are the top priority to take out for the dark side. Being noticed means being on their list, being bright and a threat means being even higher up.
