Go back into the refuge (7)
I believe the answer is:
retreat
I believe this clue is a triple definition!
'go' is the first definition.
(retreating is a kind of going)
'back' is the second definition.
(thesaurus)
'into' acts as a link.
'the refuge' is the third definition.
(thesaurus)
(Other definitions for retreat that I've seen before include "It may be secluded" , "retirement" , "snug" , "withdrawal" , "Back away" .)
