Mirror Moths

Mirror moths are not camouflaged—they negotiate. A swarm turns alleyways into house-of-mirror ethics: every step confronts you with a version of yourself that chose differently.

What they are

Each moth is thumb-sized, with wings like fractal plates—edges that repeat until the eye loses count. They do not hide against stone or storm glass; they polish the air between themselves and a witness until the corridor reflects. Customs officers on the Cordial Docks claim they can smell mirror-moth scales at twenty paces, a sweet metallic note like rain on hot brass. Harbor slang calls the scent ledger perfume.

Biologists file them under wild fey-aspected vermin. Poets insist they are neurologically smug—as if every reflection knows it is the better argument.

Where they gather

Mirror moths breed in the cooling troughs where storm glass sheds heat after harvest. Veilspire's cliff shelves give them altitude and wind; the Ash Stair gives them audience. They appear in pairs at first, then in curtains, always at dusk when roofline harmonics make the city rehearse tomorrow's weather.

Runners say the moths do not audit. They do not read binding sigils or tally breath-debt. They only offer alternatives—versions of you that turned left, signed, lied, stayed. Selene Kor is known to answer them at the cliff's edge in breath, not contract, because beasts never write names for a living.

Syndicate appetite

The Iron Syndicate prizes mirror-moth wings and grinds them into lens coatings for precision optics and mirrored surveillance plates. Possession without charter is illegal; smuggling is routine. A jar of powdered wing can fetch more than a week's honest dock labor, which is why syndicate labs keep sealed grinding rooms and why poets say the dust still argues back—coatings that show the watcher a face one heartbeat out of sync.

Guild mirror-schools forbid students from harvesting moths. Dropouts sometimes know the old wing-gloss recipes anyway.

What a swarm costs

A heavy swarm in a narrow tier can leave pedestrians disoriented for hours—not injured, but unsure which choice was theirs. Harbor clerks log these as perception drift and bill smugglers when moths are found in cargo meant for legitimate assay.

Control is imperfect. Smoke drives them off; chalk lines on thresholds sometimes hold them at bay, as if broken geometry reads as honest. No one has successfully farmed mirror moths at scale. They arrive when the glass cools and leave when the air stops arguing.
