Curse of the Crimson Throne 5E
At its height, before the death of Aroden and the departure of the separatists who founded Magnimar, Korvosa topped 23,000 inhabitants. It lost nearly 10,000 because of the resulting chaos of the time, but in the last century it regained half that many. As a result of its rapid contraction and slow re-expansion, many of the affluent sections of Korvosa remain underpopulated. With increasing trade and abundance of area into which it can expand, Korvosa could comfortably fill out to a true metropolis.
