Sparrows

The sparrows are a religious sect formed within the ranks of the Faith of the Seven. It is comprised of the lowest and humblest of the Holy Faith, and was formed in response to the suffering inflicted on the smallfolk of Westeros during the War of the Five Kings.

They are led by the High Sparrow, a travelling Septon.

In the A Song of Ice and Fire novels, the sparrows are so named because, just as the sparrow is the humblest of birds, they are the humblest of men.
