I believe the answer is:

violence

I'm a little stuck... Click here to teach me more about this clue!

'unrestrained force' is the definition.
'violence' can be an answer for 'force' (synonyms). I'm unsure of the 'unrestrained' bit.

'once veil shattered' is the wordplay.
'shattered' is an anagram indicator.
'once'+'veil'='onceveil'
'onceveil' is an anagram of 'VIOLENCE'.

Can you help me to learn more?

(Other definitions for violence that I've seen before include "Acts of aggression" , "Force, injury" , "Ferocity" , "Passion" , "Harmful behaviour" .)

I've seen this clue in The Hindu.
