The valley to the north that winds down out of the Rampart Mountains. Small and medium game are present here, but it is named after the mountain lions that prowl the scrub brush and rocky hillsides of the valley. It eventually levels out onto The Barrens.
According to Abigail Cyrildotr and Hansel Cyrilson, there is a section of the valley they avoid that they call The Ashen Vale. It appears to just be a burned out valley, but nothing new grows there and it stinks fiercely. Perhaps it is worth exploring.
