It's not on your list, but how would you feel about doing something about visiting the stars (or returning home from an interstellar visit) for either Crowley/Aziraphale or Kirk/Spock?
Absolutely! Sorry this is late, it... kind of expanded into a bit more than 500 words. I hope you enjoy it!! Thank you for asking!!
It’s a bit long to post completely here, so here’s the ink to AO3:
Crowley takes Aziraphale to visit his nebula, and gives him a practical lesson in star creation.
The Carina Nebula. His masterwork. The humans claim it is over two million years old, and he does not dispute it. Time as a concept had not yet been invented when he built the stars, of course, but he’d put so much work into it, so much heart, so much love. He can still remember it, losing himself in the act of creation. Eternities had passed him by unnoticed as he worked. Fire in his hands, elements burning white-hot around him as he painted the empty cosmos in brilliant colors the human eye can never see. Coaxing hydrogen and helium and a handful of other elements to come together, collapsing inward, spinning faster, gaining mass, gaining gravity, gaining heat. And then - fusion. The burning gas ignites, and a star is born. He knows of no better feeling in the world.
“Crowley?” Aziraphale’s soft voice reaches his ears across the emptiness of space. They hang here, weightless, in the void. Before them, his nebula. They’re near a formation the humans call the Mystic Mountain. He’d once given it another name, but then, his own name had been different then as well.
“My dear, are you… alright?” the angel asks, a soft hand resting on his shoulder.
He blinks and turns, finding Aziraphale’s concerned eyes on his face and not the majesty laid out before them. He smiles, bringing up a hand to cover Aziraphale’s fingers. “I’m fine, angel. Just… remembering.”
“Ah.” Aziraphale understands. Of course he understands. They’d all lost something in the War after all. “What was it like?”
