The fifth master rune was hidden in plain sight.
In the Headmaster's Tower — carved into the stained-glass window behind Dumbledore's chair.
Blaise didn't steal in.
He walked in.
Eyes glowing with fire, voice calm.
And when he placed his hand on the center panel—
The entire tower shook.
The Glass Cracks
Dumbledore burst into the room too late.
The stained glass behind him fractured — not with a shatter, but with a groan.
It began to bleed light, bright and unnatural. A color no one could name.
And then the glass spoke.
"Five must hold.""But five have broken."
"The seal shall return to fire."
A shape emerged from the glass — a figure of light and memory, formed from the old enchantments of the castle.
"I am the Guardian."
The Guardian's Judgment
It wasn't human.
It wasn't ghost.
It was Hogwarts' defensive soul — crafted in the era before the Founders ever stood side by side.
Dumbledore raised his wand.
"It should not have woken."
The Guardian turned to Blaise.
"You speak with Kaelen's fire.But do you carry his sorrow?"
Blaise did not flinch.
"I carry what's left."
"Then you are not enough."
Harry Arrives
Pulled by the mark, Harry stumbled into the room.
The Guardian turned to him.
Its voice fractured — shifting from male to female, from old to young.
"Althar Ardyn. You were the first to leave.""Now you return, half-formed."
"Will you claim what you buried?"
Harry whispered, "I don't know if I can."
The Guardian raised a hand — and suddenly, every wall in the room lit with memories.
Kaelen. Selene. Evaran. Ardyn.
All speaking. All breaking. All burning.
Final Scene – The Seal Demands a Choice
The Guardian pointed to the mark on Harry's wrist.
"The ring is whole.The pact is waking.The flame bearer is chosen.
Now choose your bond."
Blaise held out his hand.
"With me, you survive."
Dumbledore stepped forward.
"With me, you endure."
The Guardian said:
"With truth… you burn."
Harry looked at the flames dancing across the window's cracks.
And said…
"I choose to remember."
The Guardian smiled.
And vanished.
