Page soon featuring the eminent group (8)
I believe the answer is:
pantheon
'eminent group' is the definition.
'page soon featuring the' is the wordplay.
'page' becomes 'p'.
'soon' becomes 'anon' (I've seen this before).
'featuring' indicates putting letters inside.
'anon' enclosing 'the' is 'antheon'.
'p'+'antheon'='PANTHEON'
(Other definitions for pantheon that I've seen before include "Ancient Roman temple" , "Temple dedicated to all the gods" , "Circular temple in Rome" , "Hall of fame" , "Temple of all the gods in ancient Greece" .)
