Work Text:
The moon does not orbit the sun. The earth orbits the sun, and the moon orbits the earth. Little by little the sun's gravitational pull makes the earth stray from the circle of the moon's orbital path. The sun and the moon do not orbit each other.
That's why Wednesday has never liked when couples call themselves the sun and the moon. It is not as romantic as they are intending it, and it is wrong. Enid would say she's nitpicking. She'd be right.
Mercury also circles the sun. It is so close to the sun that it cannot leave its orbit. It goes around, around, and around, year by year by year by year by decade by decade by century by millennia. Mercury's proximity to the sun makes it too hot to support any life that would need to depend on the sun's light or warmth. Mercury is barren. Mercury is trapped.
Enid the sun, Wednesday, Mercury.
When the sun dies like all stars do, burning out and imploding, Mercury will be the first to go with it. In the blast, in the end, its proximity will be what kills it.
Wednesday dreads the sun's fiery and explosive end. She's seen this star death in her visions, the explosion taking every part of Wednesday that's ever felt joy away with it. It's all her fault, the death of a star.
All she can do is delay it.
