no problem! I play that you roll when you or the players see it. Like say they’re at a Settlement and there are 3 routes out- they would know the terrain of each of those routes. And those terrains stay the same all the way to the next Point on the Week scale. If there’s local knowledge, say they’re taking to an NPC, the terrains can be known before they’re reached. I hope that helps!
Oh ok! I was talking more about specific features of terrain.
Imagine you want to travel to some Stronghold ahead, two days of travel through Wilderness. As I understood, we roll on the Map table for 2 maps (Day Scale) to go through before reaching the Stronghold. During the travel, we know it is wilderness, how often do you roll for features or environment on the "Wilderness Table" (page 46). Each point ? Or Each day ?
I don't know if I'm really clear here sorry ! :')
