Professor Loen reaches Iris at the far ledge after examining the crossing behind them. Yuffie and Lyla wait nearby, while Desdemona’s crimson ward keeps Tessa safely inside its glow.

Professor Loen
The stones behind us are unchanged, but the threshold is older than the chamber. I found a fragment of ward knowledge I have never shared with you.
She opens her palm to reveal a thin shard of slate etched with faded silver marks. The symbols echo the sealed doorway, though their final curve has been deliberately scratched away.

Professor Loen
This construction resembles magic I encountered during my years as an Auror. I once helped contain a related working, and I believed every surviving piece had been destroyed.

Desdemona Blackwood
You believed? That is a poor foundation for warning us. If you helped contain it, perhaps you also helped create the conditions for its return.

Tessa Vale
The ward is quiet, but I can still hear the chamber listening. Professor, is this related to the presence that used my voice?

Professor Loen
Possibly. I cannot claim certainty. But if the old working survived beneath Hogwarts, then opening this threshold may have awakened the part we failed to contain.
“I compare the slate with the chamber markings”
SUCCESS (Legendary Lore, rolled +1)

Professor Loen turns the slate shard between her fingers, then offers it across the space between them. Iris accepts it carefully, borrowing its cold weight for the comparison.

Iris Evergreen
The slate’s surviving curve matches the chamber’s three clusters, but its missing ending belongs to a different sequence.
Iris holds the shard beside the pale markings in the floor. The silver scratches align with the chamber’s record of the opening and listening presence, while the scratched-away curve corresponds to the deeper descent.

Professor Loen
You have found the distinction. The slate records the older working’s entry, but this chamber preserves what happened after it was altered.

Desdemona Blackwood
Then the missing curve is not damage from age. Someone removed the part that would identify the alteration.
When Iris angles the shard toward the blue darkness, its faded silver briefly reflects a fourth cluster beneath the water. It matches the chamber’s deeper mark exactly, proving the slate and the markings belong to the same working, but not the same moment.

Tessa Vale
So the presence did not make the chamber. It entered an older path and changed what the path was meant to do.

Iris Evergreen
Professor Loen, please explain how you helped contain the old working.
Professor Loen studies Iris for a long moment, then lowers the slate. The blue darkness presses close around the group as she finally answers without evasion.

Professor Loen
I was an Auror then, and still believed every dark working could be dismantled cleanly. We found its chamber beneath another school, with a living focus already attached to the foundation.

Professor Loen
I severed its command paths and bound the remaining pattern into a threshold. But I could not destroy the source. I chose concealment instead, and reported the working as eradicated.

Desdemona Blackwood
You hid a surviving danger from the authorities, from Hogwarts, and from us. That is not containment without a cost.

Professor Loen
You are right. My silence preserved my position and endangered yours. I will surrender the old case records to you, Iris, and answer every question, but I can no longer demand your trust.
