Hollow void separating the stars, soulless character in the centre of Ball Room (5,5)

'the centre of ball room' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'hollow void separating the stars soulless character' is the wordplay.
I cannot really understand how this works, but
'hollow' could be 'empty' (synonyms) and 'empty' is found within the answer.
'character' could be 'space' (space is a kind of character) and 'space' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...

'in' acts as a link.

Can you help me to learn more?
