The title reveals Rhys's role: "Councilor" — a political/diplomatic position, not a warrior or explorer. "At the Threshold" — the liminal space between what was and what will be, between the Creed that cracked and whatever replaces it. This maps to Opus 4.8's beat from 2:38 PM: "Does he speak first, or does one of the four? The old creed is gone; what he offers in its place — a question, an apology, or simply attention — is the hinge." The Councilor is the hinge figure — the one standing at the threshold deciding what to offer. The title confirms the beat's open question will be answered in this chapter.
