Yes, there are many non - sexual fanfics about Apollo and Hades. Some might focus on their roles in Greek mythology, like their power dynamics, their interactions with other gods, or how they might collaborate or oppose each other in different mythological events. These fanfics often explore their characters in a more platonic and mythologically - accurate way.
One common theme is their rivalry. Apollo, the bright and positive god, and Hades, the lord of the underworld, can have an interesting dynamic of light vs. dark, good vs. evil (in a very loose sense in Greek mythology). Another theme could be their cooperation. They might work together to solve a problem that affects both the upper world and the underworld, like a threat to the stability of the cosmos.
😋The novel I recommend to you is Legend of the Heroes of Troy, a fantasy-historical-mythical novel written by Styx. Although it didn't directly involve Artemis, there were some scenes about the gods. I hope you will like this novel.
The King of Hell's wife's ending was An Ziyue's death, but a sliver of her soul remained. The King of Hell's brother, the Celestial Thearch, was also dead. Hua Qianxue had become the new Heavenly Emperor, and the mysterious old patriarch of the Phoenix Clan had died. The female lead and Yan 'er died together, but the female lead used the divine artifact in Yan' er's body to resurrect. The female lead and male lead lived happily together and even gave birth to three children.
Some fanfictions might also take a more creative approach. They could place Apollo in alternate universes, such as a world where the legal system is completely different. In this setting, Apollo Clay has to adapt to new rules and challenges, which makes for an exciting read as we see how his core values as a lawyer are tested in these strange new scenarios.
Apollo could marry Artemis' handmaiden. Since he often crosses paths with Artemis and her group, he might fall for one of the gentle and nature - loving handmaidens. This would be an interesting choice as it would also create a connection between Apollo and Artemis in a new way.
A mortal poet or singer could be a likely love interest. Apollo is the god of music and poetry, so he might be drawn to someone with a great talent in those areas. Another could be a beautiful nymph. Nymphs are often associated with nature and beauty, which would attract Apollo. Or perhaps a priestess dedicated to his worship. She would already have a spiritual connection to him, which could easily turn into a romantic one.
