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 it can be defined by this definition.

'hollow void separating the stars soulless character' is the wordplay.
I cannot quite understand how this works, but
'hollow' could be 'empty' (similar in meaning) and 'empty' is located in the answer.
'character' could be 'space' (space is a kind of character) and 'space' is found in the answer.
No letters remain.
This explanation may well be incorrect...

'in' acts as a link.

Can you help me to learn more?
