I can see a bit of an issue with making it a quest though. Logistically that is. Who owns a burned castle if it’s been rebuilt? What’s to stop a player from letting many keeps be destroyed to rebuild them for a specific faction? If the faction that owned the castle before it was destroyed is hostile, does the quest never occur? Granted, if they’re hostile chances are the location was never used to begin with, but relations do change over the course of a game. A down castle absolutely changes patrol generation which makes roads immediately more dangerous. Castles and settlements definitely need to be restored, but whether that’s from a quest, event, or other mechanism is up in the air.
