Druidry, like Asatru, is a modern reconstruction of an older faith. The original Druids were a professional class with great political power among the Celts. This group was crushed following the Roman invasion, but their legends survived. The practices of modern Druids are based on what is known of the beliefs and practices of the ancients, but updated for modern times. As with Asatru, it would be impossible to practice the faith as it was originally conceived because the world has evolved far beyond anything the Druids could have imagined.
