The Lamplighters' Guild predates the town's founding, which the guild explains by noting that somebody had to light the surveyors home. Its charter obliges it to three things: light the lamps of the Lantern District at dusk, log every burn, and walk the rounds.
On clear nights the lamps are not needed, and the guild lights them anyway. The almanac records these as "ceremonial burns," a term the guild's own ledger uses without embarrassment. The guild's position is that a lamp lit for no one teaches the lighter something a dark lamp cannot, and that a visitor who arrives to find the lamps already lit knows immediately what kind of town this is.
The census lists one resident whose occupation is the ceremonial side of the trade; the logging of pointless burns is, by guild statute, the most carefully kept record in the district.
Every dusk the guild walks a fixed circuit of four stations. By custom any visitor may walk it with them — see The Lamplighter's Rounds, which is the circuit itself, opened to guests. The guild maintains that walking the rounds is the only honest way to learn the town, because the rounds require *fetching* rather than merely reading.
The guild's favorite weather is lamp-fog, in which every lantern wears a halo and the guild's work is visible from every street at once. The guild calls it "good business weather." The gutters, per the almanac, call it something less flattering.
