I love what you've done with the prompt and with Celebrían's character as well. The line "her mother was not merely her mother but a figure of legend too" is so perfect. Even for me, it's sometimes difficult to wrap my head around how MASSIVE characters like Galadriel are, and you've conveyed that so well in just a few words.

I like how you've made Celebrian both a maker and an effective spy, here.

She seems to have turned being overlooked into a strength.

"a recurring glimmer of bright gold that remained" seems very apt, for Galadriel.
