"I've never done anything to you..."
She is very quiet and soft-spoken, hardly ever gets angry, and is very loyal to her friends and family. She prefers to avoid fights and confrontation.
Firebending (which she excels at)
Her family was very wealthy, so money was never a problem for her. She is the youngest of six children, all who are firebenders, and excellent ones at that. Because of this, she is very pressured to succeed in firebending. Lien has a tough time making friends because of how quiet she is. As for the war, she thinks it's barbaric and wrong, but she refrains from speaking her mind. Such words are traitorous.
