Just an overview to set your expectations.
MC - orphaned boy, kinda stupid but actually clever. Yeah, idk if you get that. He's not OP too, so bye if you expect him to be. He just wants to get back in the present but he's stuck in Ancient Greece. Classic slow rise to power, this is.
Romance? - did I put a romance tag? Yes, I guess I did. Is there romance in the story? Almost 60 chapters in and there's no sign of that. I only put the tag there for the far, far future. I'm BAD at writing romance so that sht will happen in the very, very far future of this novel if I'll even allow it. Also no harem, Greek stories you prolly know are already full of that.
Adventure - Yes. High-octane even with a touch of stupid from time to time. Era hops. Many characters, both Greek ones and OCs. Yes, OCs. This is not a fanfiction, luh.
Plot - time-travel here and there, some twists and turns, but most twists will happen in Vol. 2 (Age of Heroes) as the events of Vol. 1 will only pave the way for the grander scheme of things. Might be quite a drag, but essential.
Lore - yeah, I inserted funfacts every now and then. Myths aren't accurate and most have multiple versions. Not everyone appreciates lore and figurative writing, so bye again. Just correct me if I'm wrong.
Comedy - this is a GAG novel mostly, don't expect me to be serious all the time. Expect dumbassery of some gods, the Greek Pantheon is full of bullcrap. They aren't perfect, luh. If u get the puns and references, congrats.
Research - hell, I spent time doing research, but I don't guarantee the accuracy of everything. Lemme tell u that if you're new to greek mythology, reading this might interest you to that sht. So go to the auxiliary chapter. There's my caveat for that.
Isekai? - Strictly speaking, no. Isekai means 'another world'. MC wasn't transported to another world. He went back in time - to when the world was still young. You can call it, an 'isekai-in-disguise' (much like Dr. Stone, same world, just another timeline.)
