Mountain Map
UnderworldRoot
On the Mountain map, the 6 closed path markers cover the darker excavated paths, and clearings aren't adjacent across a closed path (it still divides forests). Once per turn in your Daylight, with any of your pieces in either clearing it links, you may spend a card to remove a closed path for good and score 1 point. The central clearing with the Tower is the Pass: if you rule it at the end of your Evening, score 1 point.
