Rose is the dark Dragoon. She is in love with Zieg. This is written back when she still was young and innocent, before Zieg died and she became bitter. She is talking about how her love has saved her from a dark place. Zieg saved her and she is trying to help him as well through a hard time.

Rose -
Hiding in the darkened room,
Playing lady knight.
I fear the sight of my own tomb,
But I know what is right.

Once it was too hard to move,
In the darkness I was lost.
Now I have something to prove.
He melts away the frost.

Flames of passion for the cause,
Burning hope and power bright.
He sets alight the old world's laws.
He even lights my lasting night.

We're just youths who lost our way.
He's the one who found it first.
I've been pulled back to light of day,
For better or for worse.

Love will bring me to my home.
Our people will be free.
I never will be left alone.
He, in turn, has needed me.
