Arien is another Dark-Huntress. The daughter of a thief, she was born with the gift of second-sight. As a result, she dedicated her life to helping others. Until an angry clansman blamed her for the death of his wife. 

Accused of sorcery, she and her father were trying to escape into the hills when she was betrayed by the man who swore he would love her forever. Her father was hanged and she was burned as a heretic.

Since then, she isn't overly fond of men and spends most of her time helping Zoe harass the other Dark-Hunters.
