Wiccan or druid (5)
I believe the answer is:
pagan
'wiccan or druid' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for pagan that I've seen before include "A heathen, not a Christian" , "Non-mainstream religious believer" , "Person without any conventional religion" , "One who follows a polytheistic or pre-Christian religion, but not a Jew" , "One who does not acknowledge a god" .)
