This is Lane. The rhythm of this chapter is generally strong—it has the cadence of a high-stakes political thriller draped in silk and frost. However, there are moment where the prose gets "sticky," catching on redundant adjectives or dialogue that feels a bit too much like a stage play rather than a conversation between two exhausted power-players.

Here is my line-level audit of Chapter 5.

### 1. STRENGTHS TO PRESERVE
*   **The Post-Adrenaline Chill:** The physical description of the magic’s aftermath is tactile and grounded. *“The obsidian sand was still hot enough to hiss against the hem of Dorian’s frost-rimed robes...”* This establishes the elemental stakes immediately without a data dump.
*   **Tactile Romantic Tension:** The "thermal hunger" concept is a fantastic internal engine for the romance. The passage where Dorian feels his marrow might crystallize if Mira lets go is the strongest character beat in the chapter. 
*   **The Power Dynamic Shift:** The moment Dorian lies to Vane—and Mira instinctively picks up the beat—is excellent. It shows them as a "Union" through action before they discuss it in dialogue.

### 2. MUST-FIX — CONTINUITY
*   **The Proctors' Location:** When Vane arrives, the text says the proctors (Kaelen and Lyra) are kneeling by the students. Later, Dorian tells them to "take them to the Waygate." However, Vane then says *“I am placing an Imperial Seal on the doors. Only the Chancellors may enter or leave.”* 
    *   **The Error:** If the seal is placed immediately and Vane is "guarding" the exit, the proctors are either trapped inside with them or they vanished through a Waygate that Vane should technically have jurisdiction over. 
    *   **The Correction:** Clarify that the proctors depart *before* Vane's guards finalize the "Imperial Seal" on the Sanctum specifically, or clarify that the Waygate is a separate, sanctioned medical exit.
*   **The Sanctum Layout:** In Chapter 5, Vane says he is *“commandeering the lower apartments of the Chancellor's wing.”* At the end of the chapter, Dorian and Mira enter the Sanctum and the doors are sealed. 
    *   **The Error:** If Vane is in the "lower apartments" of the same wing, the "Total Privacy" Dorian claims they have is contradicted by Vane’s proximity.
    *   **The Correction:** Ensure Dorian acknowledges that even their whispers might be heard through the floorboards/vents, heightening the tension of their "performance."

### 3. MUST-FIX — CLARITY
*   **The "Seal" Confusion:** 
    *   **The Passage:** *“Above them, in the heart of the Sanctum, the Imperial Inquisitor’s seal rested on the locked brass handle of their shared quarters...”* 
    *   **The Issue:** Earlier, the seal was a *“glowing purple ribbon of light”* across the main door. Now it’s on a *“brass handle of their shared quarters.”* Is there one seal or two? Is the seal on the front door of the apartment or their bedroom door?
    *   **The Fix:** Consistent terminology. If the whole suite is sealed, focus on the main entry. If their bedroom is sealed, specify why they aren't just sleeping in separate rooms within the suite since Vane is looking for "nocturnal stability."

### 4. OPTIONAL SUGGESTIONS
*   **DIALOGUE TIGHTENING:** ORIGINAL: *"I came up with it because the alternative was a summary execution. Would you have preferred I told him we accidentally blew up our students because we're so poorly integrated that your temper makes my water boil?"* 
    *   **SUGGESTED:** *“Because the alternative was an executioner's block. Would you prefer I told him your temper makes my water boil?”* 
    *   **RATIONALE:** The original is a bit "as-you-know-Bob." Dorian is smart; he doesn't need to explain why he lied. The shorter version is punchier and more in character for a "Glacial Dean."
*   **ADJECTIVE AUDIT:** ORIGINAL: *"The obsidian sand was still hot enough to hiss against the hem of Dorian’s frost-rimed robes..."*
    *   **SUGGESTED:** Keep as is, but watch the "jagged sentinels," "jagged spike," and "jagged mountainous ice forest" repeats. 
    *   **RATIONALE:** You use "jagged" four times in three pages. Swap one for "serrated," "splintered," or "barbed."
*   **WORD ECONOMY:** ORIGINAL: *"He wore the long, charcoal-gray mantle of the Ministry of Oversight, cinched with a belt of heavy silver keys."*
    *   **SUGGESTED:** *"He wore the charcoal mantle of the Ministry, cinched by a belt of heavy silver keys."*
    *   **RATIONALE:** "Long" and "gray" are implied by "mantle" and "charcoal." Trust the noun to do the work.

### 5. FORBIDDEN CHANGES / NON-GOALS
*   **Do not tone down the "Cheap Romance Broadsheet" line.** Mira calling out the "common heart" dialogue is essential. It prevents the book from becoming too melodramatic by acknowledging the trope within the text.
*   **Do not remove the "Tether" descriptions.** The "somatic bleed" and the humming frequency are the unique magical signatures of this series. Keep those sensations central to every scene they share.

### 6. VERDICT

**REVISE**
The continuity regarding the Imperial Seal's physical location and the timeline of the proctors' departure needs a quick polish to ensure the "locked room" logic holds up. Once the geography of the Sanctum and the Seal is tightened, this is a very strong mid-point chapter.
