The Romun Empire is a large empire controlling large parts of the Eresian continent and the Medo Sea, spreading as far as Xandria. It's seat of power lies in Romn, the empire's capital city. Adol Christin's interests tend to clash with the Romun Empire, often leading to violent encounters between Adol and representatives of the empire. As such, the Romun Empire can be seen as one of Adol's main recurring enemies, alongside the Clan of Darkness.
The current emperor of the empire is Marcus Claudius Garmanicus.
It is currently unknown when Romn was built and when it became an empire. However, the earliest noble family known currently is Sir Carlan's family was established at around 300 years before the event of Ys VIII: Lacrimosa of Dana. It is possible that Romun Empire was built sometime before or around that time.
In Ys: Memories of Celceta, Adol, while still trying to recover from amnesia, has to hunt down rogue Romun military officers who are trying to kill all but the strongest humans. Griselda, a Romun princess who is the governor-general and ruler of Celceta, backs Adol in his quest to dispose of these rogues.
In Ys: The Oath in Felghana, Count McGuire, a nobleman from the Romun Empire who was appointed as the feudal lord of the area, closes the mine which is the main source of income for Redmont and levies high taxes.
In Ys VI: The Ark of Napishtim, the Romun Empire's army lead by Admiral Agares and Ernst conquers Canaan and enslaves several Rehdans on the basis that they are "subhuman". Adol worked with Baslam, Ladoc, and the remaining Rehdans to rescue the hostages and retake Canaan.
Ernst also took over the Ark of Napishtim, but was stopped by Adol. Since the Ark's control key Almarion was destroyed in the fight, Adol had to destroy the Ark in order to prevent it from causing destruction.
In Ys Seven, the Romun Empire just concludes the Romun-Altaginian war with the Principality of Altago. This caused the Altaginians to still be suspicious of the Eresian. Adol was under suspicion of regicide of Kiemarl becuase of this.
