Game of Thrones features many unique cultural groups. Every notable assembly of humans grows and changes with the natural push and pull of environmental factors. The people of the North are stern and firm but rigorously respectful of hospitality because their land is as unforgiving as it is quietly noble. The Valemen among the Mountains of the Moon are proud, faithful warriors raised in the beautiful, fertile valley. The hill tribes and mountain clans outside the Vale are a different breed.
