The library was nearly empty.
Not the main one — the sealed one. Deep beneath the east wing, accessed only by password, blood, and permission no one had given.
But the mark opened it anyway.
Harry's fingertips tingled as he passed beneath the rune-etched arch. A stone door slid away like it remembered him.
Dust filled the air. Magic vibrated in the walls. The air itself tasted… old.
He walked past shelves that had no labels. Past portraits that turned to look at him and then looked away.
Until he found it.
A single book, black leather, unmarked spine.
It pulsed when he touched it.
The Language of the Marked
The pages were blank at first.
But when his skin brushed the corner, text appeared — green, curling, alive.
"Written not in ink, but in inheritance."
Each word rearranged itself as he read.
"The Fifth Legacy. The House Unspoken. The Heir of Stone."
Then a name.
"Selene Arctaria Vale."
He whispered it.
The room shifted.
The book's center spread open like a wound.
A symbol appeared — identical to the one on his palm.
The Prophecy Fragment
One page burned brighter than the rest.
The words didn't shimmer. They clung to the parchment like blood.
"When the door breathes again and the Serpent's hand burns,And the child speaks the lost name aloud,The House Unwritten shall rise in memory,And the castle shall choose again —Not by hat.Not by blood.But by loss."
Harry stared.
A cold tremor filled his spine.
This was no prophecy.
This was a trigger.
Return to the Slytherin Dorms
He said nothing that night.
Not to Draco.
Not to Theo.
He lay in bed staring at the ceiling, breathing slowly, counting the seconds between heartbeats.
Because now he had a name. Selene Arctaria Vale.
And that meant she wasn't a dream.
She was real.
And somewhere — whether in memory, magic, or more — she was waiting for him.
Final Scene – Stone Movement
Somewhere below Hogwarts, stone shifted.
Not broken.
Not summoned.
Woken.
And in a whisper no one heard, the door beneath the castle spoke for the first time:
"He knows her name.""He remembers."
"Let it begin."
