Legendary flapper, while entering stark drama midway (6,4)

'stark drama midway' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.

'legendary flapper while entering' is the wordplay.
I cannot really see how this works, but
'flapper' could be 'roc' (mythological bird of prey) and 'roc' is found in the answer.
'while' could be 'as' (eg 'while I walked' means 'as I walked') and 'as' is found in the answer.
'entering' could be 're' (I've seen this in other clues) and 're' is found within the answer.
The remaining letters 'baa' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
