The northern mountains
An intricate, seemingly friendly massif rises nearly from the edge of the Bay of Biscay which often sends its fleet of clouds to collide in these mountains, dumping constant rainfall in the midst of dense fog. In winter, despite its modest altitude (peaks barely reach one thousand metres above sea level), the rain becomes snow.
As such, the landscape found in O Xistral seems to be a replica of mountains in the north of the British Isles or Scandinavia, with large areas of peatland enveloped by fog and mystery. So much so that there are only traditional human settlements in the valley, at a much lower altitude, where average temperatures are much higher. The rainfall and terrain gives rise to numerous rivers that flow into different basins.
The mountains of this range were exploited only through extensive grazing using cows and horses that, even today, roam free. Well into the last century, attempts to cultivate pine were made with mixed success due to the harsh climate. Currently, the major energy source of these mountains -wind- is intensely exploited.
