Stage conclusion for story (6)
I believe the answer is:
legend
'story' is the definition.
(legend is a kind of story)
'stage conclusion' is the wordplay.
'stage' becomes 'leg' ('leg' can be a synonym of 'stage').
'conclusion' becomes 'end' (end is a kind of conclusion).
'leg'+'end'='LEGEND'
'for' acts as a link.
(Other definitions for legend that I've seen before include "Story handed down from the past" , "Tale; caption" , "Traditional story - inscription" , "Very famous member's death" , "Former top player" .)
