Forebear needs an exotic escort (8)
I believe the answer is:
ancestor
'forebear' is the definition.
(I've seen this before)
'an exotic escort' is the wordplay.
'exotic' is an anagram indicator.
'escort' is an anagram of 'cestor'.
'an'+'cestor'='ANCESTOR'
'needs' acts as a link.
(Other definitions for ancestor that I've seen before include "descent comes from one" , "Antecedent, forebear" , "Adam was our first one" , "Enactors (anag)" , "Forefather" .)
