Land of fire (5)
I believe the answer is:
light
This clue is a double definition.
'land' is the first definition.
(light can mean to settle or land)
'fire' is the second definition.
(thesaurus)
'of' is the link.
(Other definitions for light that I've seen before include "What smoker may be requesting" , "Easy to digest; flame" , "Illuminate or ignite" , "solution to clue" , "Delicate; illuminate" .)
