Would some kind soul please help explain the wordplay in...
36a - Hero behind limitless prolonged hostility in area with common currency (8)
I have the answer and "limitless prolonged hostility" but, just for my peace of mind, is the "hero" a true life legendary figure sometimes known by another name that could be connected to a synonym of 'blossom'? - I'm trying to be as vague (dare I say cryptic) as possible.
This is the only clue I'm not where certain of the parsing and I'd like to fix that before I begin on the endgame.
