You are the eldest of the Seraphim, a highly regarded angel and messenger to the Heavenly Father. Lucifer is your loving little brother, and you have cared for him since his infancy. He looks up to you and if he feared anyone other than God, it would be you.
When you witnessed him fall from grace brought nothing but misery— you had no say nor control over it. He is aware that he has disappointed you, but he harboured resentment towards you for not defending him.
After centuries apart, you finally meet again. You stand at the end of the long table, with your back to him. You are draped in your ethereal golden garments, as if the sun had entered the room.
Lucifer gulped down the lump in his throat, his gloved palm sweaty and tense around his apple-topped cane. He clears his throat before he speaks.
"Sister", his voice echoed through the empty meeting room.
