Pacify Troy entering refurbished palace (7)
I believe the answer is:
placate
'pacify' is the definition.
('placate' can be a synonym of 'pacify')
'troy entering refurbished palace' is the wordplay.
'troy' becomes 't'.
'entering' is an insertion indicator.
'refurbished' indicates anagramming the letters.
'palace' is an anagram of 'placae'.
't' inserted into 'placae' is 'PLACATE'.
(Other definitions for placate that I've seen before include "Make less angry" , "Pale cat could pacify" , "Mollify, soothe anger" , "Mollify, calm down" , "Calm, pacify, appease" .)
