Up there: some endlessly stormy god (10)
I believe the answer is:
prometheus
'god' is the definition.
(Prometheus is an example)
'up there some endlessly stormy' is the wordplay.
'endlessly' means to remove the last letter.
'stormy' is an anagram indicator.
'up'+'there'+'some'='uptheresome'
'uptheresome' with its last letter taken away is 'uptheresom'.
'uptheresom' with letters rearranged gives 'PROMETHEUS'.
(Other definitions for prometheus that I've seen before include "Fireman" , "Prominent Greek" , "-- Unbound (Shelley)" , "Gk. hero, gave men fire" , "Greek god" .)
