Town · on the Miskatonic
Arkham
The witch-haunted college town at the center of everything — gambrel roofs, elm-shadowed streets, and a citizenry practiced at not discussing what the Miskatonic brings downstream. Every road on this map eventually leads here, and every survivor eventually testifies here.

A witch-house attic room is re-let after a century sealed; the new tenant's geometry homework starts solving itself.

Institution · Arkham
Miskatonic University
New England's quietest famous university, whose library keeps a Latin Necronomicon behind iron and whose faculty have twice saved the world without tenure recognizing it. The Restricted Section is consulted by appointment, refused by instinct.
Cited in The Dunwich Horror · At the Mountains of Madness · The Shadow Out of Time
Hooks
A visiting scholar's letters of introduction are perfect — and typed on a machine whose typeface died in 1820.
The library's call slips for one shelf mark keep going missing, in order.

Arkham Sanitarium
The archive's home ground. Ward C houses the patients who stopped being wrong — the ones whose statements match each other across decades without ever having met. Patient 1928-XIII transcribes what the deep hums; the recordings you are listening to are filed as his.
Cited in The Thing on the Doorstep · the frame of this whole catalog
Hooks
Two patients admitted twenty years apart draw the same spiral, signed with the same initials.
A discharged patient's family reports him improved, changed, and left-handed now.

Town · the coast
Kingsport
A steep old harbor town of crooked lanes and sea-fog, beautiful enough that visitors forget to ask why the highest house on the crag keeps its lights burning for no listed resident. Kingsport dreams more than it fishes.
Cited in The Festival · The Strange High House in the Mist
Hooks
An investigator inherits an invitation — not a house, an invitation — to the festival held every hundred years.
The fog comes in on schedule; one morning it goes out with something's tracks in it.

Arkham · the open Atlantic
Town · the Manuxet mouth
Innsmouth
The shunned port. Half-empty since 1846, raided by the government in 1928, and still — officially — a customs anomaly. The Esoteric Order of Dagon holds the old Masonic hall, the gold refinery works odd hours, and the bus to Arkham runs mostly empty in one direction.
Cited in The Shadow over Innsmouth
Hooks
The refinery quietly reopens under new ownership with old faces.
A genealogy service refunds an investigator's fee with a note: "Do not pursue."

Sea mark · offshore Innsmouth
Devil Reef
A black line of rock a mile and a half out, barely above water at high tide — and, at certain moons, above it in company. Obed Marsh's bargains were struck here, and the depth charges of 1928 did not reach what keeps the appointments now.
Cited in The Shadow over Innsmouth

A salvage crew wins the wreck rights at auction, cheap.
The new lighthouse keeper's log is meticulous, until the entries begin answering him.

Innsmouth · Y'ha-nthlei below
City · beneath the Atlantic
Y'ha-nthlei
The many-columned city under the deep beyond the reef — cyclopean, phosphorescent, and patient. Its people do not die, and its ledgers are kept in tribute and blood. Marked on this chart in the only sense that matters: it is exactly where it has always been.
Cited in The Shadow over Innsmouth · Dagon

Something asks, through an intermediary with too few blinks, to buy back an item raised by trawler.

Devil Reef, far above
Village · the upper Miskatonic
Dunwich
A decayed huddle of farms in a fold of the round hills, where the whippoorwills time their calls to the dying and stone circles crown the summits. The Whateley name is spoken the way one prods a bruise. Since 1928 the village signposts have been removed — by the county, officially.
Cited in The Dunwich Horror
Hooks
A land agent is buying the farms around Sentinel Hill for a client who signs in an unreadable hand.
The whippoorwills have started gathering at one particular house, in daylight.

Sentinel Hill · Cold Spring Glen · Aylesbury
Summit · above Dunwich
Sentinel Hill
The bald summit ringed with standing stones, table-topped by an altar older than the tribes who feared it. May Eve and Hallowmass light fires here that no farm admits to setting. This is where the Dunwich horror was called, and where it was sent back — mostly.

A university surveying team finds the stone ring one stone richer than the 1912 photographs.
Someone has been maintaining the altar. The nearest farm insists it's birds.

Town · the pike
Aylesbury
The last ordinary town before the hills — feed store, courthouse, a pike named after it, and a firm local policy of not continuing conversations about Dunwich. Investigators provision here; so does everything else.
Cited in The Dunwich Horror
Hooks
The feed store's biggest account pays in old coin and collects at night.
The courthouse fire of 1919 destroyed exactly one shelf of records.

Ruin · west of Arkham
The Blasted Heath
Five grey acres where nothing grows and no snow lies quite right, upstream of the new reservoir that will shortly put it — and its well — underwater. The surveyors work quickly there and decline overtime. Arkham will drink that water.
