The Brotherhood began as a compact among lift crews after a preventable platform collapse at the Three-Peaks Gap. Its members traded inspection knowledge across settlements that had previously guarded their mechanical methods as local secrets. The Long Hoist Dispute established its authority to halt a dangerous ascent, while later council recognition made certification a condition of operating major public lifts. During the following decades, the guild standardized inspection marks and emergency procedures across much of the Terraced Bastions. Its crews helped keep crossings open through storms and supply interruptions, earning a reputation for reliability. Growth also brought conflict: merchants resented delays, local operators resented outside oversight, and guild leaders discovered that control of lift schedules could secure political concessions. The Brotherhood now faces pressure from both sides. Infrastructure is aging, trade demands are increasing, and every closure risks isolating a community. Its members remain bound by a shared craft, but disagree over whether their duty is to protect people from unsafe systems or to preserve the guild's right to control those systems.

The Tri-Peak Cable Hub occupies a broad gallery in the Citadel of Terraces, where three bridge approaches converge above the Three-Peaks Gap. Its public floor is full of route charts, repair notices, and the steady clatter of a working test winch. Beneath it, a locked inspection bay holds cable samples, tension gauges, and the Brotherhood's oldest ledgers. The air smells of hot grease, wet wool, and iron filings; wind whistles through narrow ventilation slots even with the doors shut.
