According to Dickens, who was the original druid?

Europeans generally believe that druidism advocates nature and neutrality, and they regard the whole wasteland as a hermit at home. They let their special forces protect nature and balance the whole world. In modern fantasy literature, druids are worshippers and defenders of nature. In order to protect nature, they can fight against any force. Druid's original English name is Druid. The first half of druid means oak tree in Greek, and the second half is similar to the suffix "-wid" in Indo-European language family, which means understanding. Druids take acorns as sacred fruits, so the ancient meaning of Druids' names is people who are familiar with oak trees. The famous "Merlin" in King Arthur's time is said to be a wizard with extraordinary power. In fact, he should be a druid with considerable practice. The word "Merlin" originally refers to a druid wizard who is proficient in poetic art and visual art (divination).

In the first century A.D., Christian Romans attacked the Druid Celts. The Romans, as winners, washed away the druids, who were slaughtered in batches by Roman soldiers who rushed into the mysterious forest, and the bodies of priests were left in the sacred forest. Druids were destroyed by this massacre and have been dormant ever since. Druidism only appeared in later folk songs and poems. Since then, their prestige has fallen to the status of ordinary wizards for centuries, and their former glory is gone forever, so they can only recite sad elegies alone. Therefore, from then on to now, Druid is no longer like a religious or historical term, but has become a mythical figure. Nowadays, we can see their imitations in some interesting retro sports, but what really affects us is the caster in the game. Druids in modern fantasy literature and games are mostly based on legends before the first century A.D., and gradually evolved into a mysterious organization with natural forces.
