Some sort of Ancient Greek/roman empire and Persia star crossed lover where Tony is the son of Roman Empire au
That would be epic! There are a few Roman-esque Stony fics that you might want to check out:
Muses by Era_Penn: Lord Anthony Starkson, cousin of the great Caesar, was cursed by the goddess Venus never to see his true reflection, but instead a hideous monster.Steven Rogerson, who holds great glory on the battlefield, wants to show him just how beautiful he is.
What do you do when the Roman Empire you were raised to love consigns you to the sands of the arena? Antonius is a prince of the Dacians, captured in war and sold as a gladiator. He yearns for his freedom. Stephanos – the last living centaur – is his fellow slave and trainer. Centuries old, disillusioned by a Rome that has become a shadow of itself, Stephanos has all but given up on life… until he meets Antonius, and both of their lives are forever changed.
With This Shield or On It by @laudatenium (WiP): “Well, there are men, there are gods, and there are those of us who are both, yet neither,” Steve nodded at him.“Maybe you’re a hero,” Tony grumbled, “but not all of us are heroes.”Steve traded a look with the others, then smiled cryptically at Tony. “Wait and see.”—After the Trojan War, the next generation of great heroes arises, and the Prince of Athens falls in love with the King of Korkyra.
For a precious moment suspended in time, they can lose themselves in each other.
The Emperor’s Fury by valtyr:
Steve is an ex-gladiator. Tony wears a toga. Together, they litigate civil cases. Also a surprising amount of boating.
The Heart of the Temple by captainshellhead and vibraniumstark: After an expedition to find an ancient relic goes awry, Tony finds himself magically bound to a Roman soldier who has spent the last two thousand years guarding the temple, and who is now bound to protect him from harm.Stranger things have certainly happened, but Tony is having a hard time coming up with them now.
Per ardua ad astra by Missy_dee811: Antonius is the first-born son of a Roman senator. His father ruled with an iron fist.For Antonius, the best day of his life is the day he meets Stephanos, a slave born in Roman-occupied Britain, who would, one day, become the best gladiator of his age.
The Creature from Stark Sea by orphan_account:
An ancient Greek/Roman AU in which Tony is a tentacle monster and Steve is his new found human sex toy.
Make Me A Believer by allstarspangled (WiP):Tony had not always been Anthony Edward Stark.
A long time ago (And I mean a really fucking long time ago. Gods.)
He had been going by something a little bit different.Or the greek fusion fic that no one asked for. Where Tony is Iron Man, Avenger of the Earth, and Hephaestus, god of fire and metalworking.
Greek Mythology AU (series) by oftheashtree: (I read a text post on Pinterest about how Persephone found the Underworld on a little frolic through the nearest meadow and decided she liked it there – she wasn’t kidnapped or whatever – and all I could think about was a lonely Tony Stark, God of the Underworld, and a plucky pre-serum Steve that didn’t go where he was told and fell in love with the rough and tumble mechanic that made beautiful things out of scraps and didn’t quite know how to love. Save me.)“And the Greeks feared him more than his husband because Hades could be reasoned with but little Steve Rogers was the fire that fueled the Underworld and the smoke that suffocated sinners.”(Also known as “The Author has FEELINGS about Tony Stark being The Merchant of Death and Steve Rogers loving him anyway”.)
