oh - i've written a whole thing about this, actually!
norlund is the bright blue dot - due north of
@jellyjam 's village - almost right on top of the border with the cloudnap mountains and sunset pines. i headcanon it to be a region of semi-mountainous forest, with one particular localized area that gets way colder than is normal. the researchers of norlund currently theorize that this happens because of a unique geologic coincidence, or possibly the influence of stray magic... or both. regardless, it is so cold year-round as to be almost inhospitable. perhaps it might have been marked off with warning signs and left alone, were it not for norlund's founders, who love the cold despite the challenges that it brings. norlund has now become a haven for not-cats who like to enjoy a year-round, unending winter!
i might end up changing norlund's corresponding map location if (when?) we get access to areas outside nestor's wood, but for now i'm quite happy with it, and it plays well with the canon that all villages are currently located within the wood
