The slate grows cold in Iris’s hand. Its incomplete curve fills with pale light, and a thin line appears beneath the black water, slipping away from the false trail toward a sealed passage under Hogwarts’s east foundation.

Professor Loen
That is an observation channel. It survived the alteration, though only barely. Reading it may show us what happened after the working was changed.
The pale line trembles beneath the water, illuminating a narrow arch concealed in the far wall. No current returns from it, and the sealed stones bear the same missing curve as the slate.

Desdemona Blackwood
Then the passage is another threshold. Tessa stays behind the ward, and nobody touches that channel without understanding its price.

Tessa Vale
I can feel the listening presence farther away now. It is not Morrow’s voice, but the channel remembers the shape of it.
Yuffie shifts nearer to Iris while Lyla remains beside Desdemona and Tessa. Professor Loen keeps her wand trained on the luminous line, careful not to interrupt its slow movement toward the hidden seal.

Professor Loen
Iris, the channel is waiting for a reader. If you follow its record, be prepared for the possibility that it will consume another piece of your memory.
“I read the observation channel despite the memory cost”
SUCCESS (Legendary Lore, rolled -1)

Iris presses the slate shard toward the luminous observation channel and reads its surviving pattern. The pale line opens into layered images beneath the black water.

Iris Evergreen
The channel records the alteration from inside the working.
The record shows Professor Loen’s earlier containment: command paths severed, the living focus bound into a threshold, and a second hand changing the pattern afterward. The hidden passage was redirected, not destroyed.

Professor Loen
That is the moment I missed. Someone entered the sealed working after I bound it, then turned its observation path toward Hogwarts.
The final image identifies the altered channel’s purpose: it was made to observe a chosen magical heir and wait for her presence to complete the descent. The knowledge settles clearly, while one tender detail of Iris’s parents fades from memory.

Desdemona Blackwood
The channel has named its intended subject. Iris, it was watching for you, but Tessa’s choices remain her own.

Tessa Vale
Then we know what it wanted, even if we still do not know who changed the working. I will not let it choose my part again.

Yuffie
Good. We learned the truth, and the creepy channel did not get to decide anything for you. That counts for something, adorable genius.
“I ask Desdemona to analyze the residue”
SUCCESS (Great Diplomacy, rolled +1)


Iris Evergreen
Desdemona, please analyze the residue around the channel. I want to know what changed the working and whether it still threatens Tessa.
Desdemona accepts the request without argument. She draws two fingers through the pale residue beside the sealed passage, keeping her crimson ward settled around Tessa.

Desdemona Blackwood
The residue is not the severed channel. That path is truly gone. This is older binding-work, altered afterward to observe a chosen heir.
Her magic separates the residue into fine layers. One bears the original containment, another carries the later redirection, and a final trace records the channel’s attention settling on Iris.

Desdemona Blackwood
The alteration was deliberate, but it is inactive now. It marked Iris as its intended subject, not Tessa as its master or servant.
The last pale flecks collapse beneath Desdemona’s hand, leaving only harmless dust on the stone. The sealed passage remains quiet, and Tessa’s ward shows no answering disturbance.
“I ask Loen who changed the working”
SUCCESS (Great Diplomacy, rolled +1)


Iris Evergreen
Professor Loen, who changed the working?
Professor Loen goes still. The harmless dust lies between her and the sealed passage, while the blue darkness reflects in her lowered wand.

Professor Loen
I know the hand now. It was Severin Voss, my partner in the old dark circle, the only person who knew I had bound the working instead of destroying it.
Her admission settles heavily. She turns the slate shard over, revealing a tiny hooked mark hidden beneath its worn edge, matching the alteration residue exactly.

Professor Loen
Severin survived the containment, vanished before I could find him, and possessed both the knowledge and the motive. He redirected the observation path toward Hogwarts.
The sealed passage remains inactive, but the answer gives the old alteration a human author. Professor Loen raises her eyes, no longer hiding behind uncertainty.

Professor Loen
Severin Voss changed the working. If he still lives, he knows why it was waiting for you.
