'authority' is the definition.
(thesaurus)

'epics remade with top stars one conveys' is the wordplay.
'remade' indicates an anagram.
'with' is an insertion indicator.
'top' suggests taking the first letters.
'one conveys' becomes 'alit' (I am not sure about this - if you are sure you should believe this answer much more).
The first letter of 'stars' is 's'.
's' put within 'alit' is 'alist'.
'epics' is an anagram of 'speci'.
'speci'+'alist'='SPECIALIST'
