Pagan
Celtic Paganism still has strong roots in the peoples of Britain even if more and more of the nobility are turning to Christianity. Some Manors still hold true to the Old Ways, and still honor the Great Gods as well as their own house pantheons. This religion is deeply rooted in nature, possessing neither good nor evil, but instead an ever-changing landscape of light and dark.
