It was very interesting to note that upon civil war breaking out, it stopped counting as a town for the purposes of the Coin's Night Prowler face. Something to bear in mind in the future.
It makes sense; it seems like Night Prowler works, thematically, by letting you disappear into the streets. Just another anonymous face in the crowd. But in a period of civil unrest, everyone is tense and eyeing up everyone else to see what side they are on: a shift in default identity from
civilian to
combatant, and Night Prowler doesn't let you be a faceless ignored combatant.
My tentative interpretation, which I don't anticipate us getting the chance to test any time soon: the reason why it failed here is because it's a
greenskin settlement, and greenskin society exists on a total war footing. Therefore, when a greenskin settlement gets riled up,
nobody is in Civilian Mode, everyone is in Combatant Mode, and Night Prowler can't do its magic. My prediction is that if we were to enter a
human city riven by civil strife, it would work much better, because even when humans are on edge and worried about enemies within their settlements, civilian life still
exists.
