Aim to follow member’s story (6)
I believe the answer is:
legend
'story' is the definition.
(legend is a kind of story)
'aim to follow member's' is the wordplay.
'aim' becomes 'end' (I've seen this before).
'to follow' says to put letters next to each other.
'member' becomes 'leg' (leg is a kind of member).
'end' put after 'leg' is 'LEGEND'.
(Other definitions for legend that I've seen before include "Footnote" , "Former top player" , "Story about mytical beings" , "famous player?" , "King Arthur" .)
