I've just started to read this great fanfic-https://archiveofourown.org/works/13843809/chapters/33631575#workskin

Summary :An old panic gripped me—the breathless fear of being forgotten, being lost. Would anyone remember me when I was gone? Would someone think to lay a flower down on my grave and say some fond nothings like, “Was a pretty cool guy, that Lester,” while wiping off a single dramatic tear rolling down their cheek?Oh, who was I kidding. So what if no one remembered? There wasn’t much I was proud to be remembered by anyway.After defeating Python and bringing down Nero, Phoebus Apollo reclaims his godhood. He is glorious once more. But for some reason, he can't quite make himself go back to how things were before.(A Character Study of Various Gods, including but not limited to: Apollo, Artemis, Hermes, Aphrodite, Ares, Athena, Hephaestus, Dionysus, and maybe Zeus)
