The 66 places the game itself names — the vocabulary every NPC, house,
hunting ground and boat trip is filed under, rather than the wiki's
articles about them. 24 of the 66 have no article at all, Thais above
all, and report location: null; /locations is the other side of that.

Because a city is not an article, its id is this API's own key rather
than a wiki one — the only stable number the vocabulary has.

What stands in a city is a page of its own: /cities/{city}/houses,
/npcs, /hunts, /raids and /npc-destinations.
