Hello Darkforest, the druids were the keepers of herb lore, divination, spell craft, clan history and story craft, and communicators with the Celtic Otherworld. they did not write things down because they did not want the knowledge to get into the wrong hands. now, the term is interchangeable with Neo-paganism. you might like the books of Kristopher Hughes, and he has a website. Kristopher is a druid.
