Forodwaith wanted to correct for the "criminal" underwriting of Arwen by specifying a drabble that depicted her apart from Aragorn.
And so Arwen seeks her melody anew, in imperfect memory's depths–
The generosity of flame:
White-silver
Self-consumptive fire
In loving leaves
Her light for all.
This time, the image holds. Through tears, Arwen smiles. Tribute to light not past, but passed, she sings her mother's song.
