As the players work their way from Lilorn into the reaches of the Sword Mountains the road continues to narrow.
The path is wide enough for a cart and maybe a single person beside it. The tree line eventually begins to fade away and the path turns into a proper mountain road, with steep grey stone on one side and a sharp drop away on the other. Every so often the path widens just enough for 2 carts to maybe squeeze past each other. As the party continues the cold wind becomes stronger as it howls through the various valleys.
