Druid [3] [4] means the goddess of the forest in Roman and Greek mythology. It is said that every oak tree is inhabited by elves, and these tree spirits convey the Oracle to mankind through druidism.

Celtic is a people scattered in Gaul, Britain, Ireland, Europe, Asia Minor and the Balkans from the 5th century BC to the 1 century AD. Druid priests are proficient in divination, meticulous in rituals, and good at calendars, medicine, astronomy and literature ... At the same time, they are also synonymous with law enforcers, bards and explorers. Both men and women can become druid priests, and they can act as priests, wizards or prophets within the family, and they also enjoy a high status in society. Some historians also equate Druid priests with Indian Brahmins, Persian monks (Magi), Egyptian priests (priests) and shamans. At first, because Celtic was a matriarchal society, only women could be druids, and then men gradually joined.
