Fairy king from Borneo originally (6)
I believe the answer is:
oberon
'fairy king' is the definition.
(Oberon is a mythical fairy king)
'borneo originally' is the wordplay.
'originally' is an anagram indicator.
'borneo' with letters rearranged gives 'OBERON'.
'from' is the link.
(Other definitions for oberon that I've seen before include "Play King" , "Spirited king" , "Satellite" , "King of the fairies (AMND)" , "Shakespearean role" .)
