A Worthy Foe.
Against all odds, she succeeded in becoming a titan of law. It was a miracle that she did. But now she is plagued with the repercussions of her actions.

Now, she is at it again. That's why she is in the immortal lands. She is looking for a way to reinforce her inner world and gain control of her concept.
