Genesis setting (4)
I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">genesis setting</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for eden that I've seen before include "Perfect place" , "Tory Prime Minister, 1955-57" , "PM, 1955-57" , "5,27 [PRIME MINISTER]" , "Former British PM - unspoilt paradise" .)
