oathbreaker
One who betrays
An oathbreaker is someone who violates a solemn promise or sworn commitment.
The word carries weight because oaths traditionally invoked divine witness or sacred honor—breaking one wasn't mere dishonesty but betrayal of something held inviolable.
The term appears often in fantasy literature and games, where it typically marks a character as disgraced or cursed: The oathbreaker was shunned by his former brothers-in-arms.
