Elucienweek Day 5 Sunshine
I still think about that whole paragraph in SF where Cassian describes how Nesta and Feyre look as if they own and command the night with their clothes in Nightcourt black, but Elain, no matter how much she claimed to be a part of that court, it sucked the life from her. Black drained her of color, the girl who craves sunlight, who is constantly turning towards the sun and chasing away shadows.
Who would have thought the mother gave her a mate filled with sunshine, filled with warmth. Elain has been in the shadow of others for so long, but with Lucien she has the perfect chance to step into her light.
The placing of this lighting is purposeful. Lucien, who has a light within him, has been cast in darkness through all the things he's been through and carried. His own light behind him, but still reaching out to Elain.
Elain is cast in shadow from where she currently is in the story, but part of her is illuminated in light from Lucien. She can see the light in him that he may not be able to see. If only she can take his hand, and permanently step out of the shadows, of the dark, into the light that she has always been turning towards.
