Freya had quite a dark storyline, with tragic things happening. She was very useful later in the game when her Dragon's Crest skill had been powered up. It always does 9999 damage, even if the enemies are protected or Freya is under status ailments. For example, the damage done by Steiner's Shock is greatly reduced when the enemy is using Protect, or when Steiner is under the Mini status. Dragon's Crest doesn't have this issue.
