Herculon II of Eros was the eight emperor of the Realm of Eros. He succeeded his father Aeson IV and was himself succeeded by his son Herculon III.

The period of Herculon II’s reign is known as a troubled period in the Realm. An example of this is the Dispute of the Unpaid, which resulted in the murder of Graius “The Stupid” in the Erosian Senate in the year 166 and the starting attacks by barbarians of the Brear tribe on Erosians villages to which the emperor had no clear and one-sided answer.

Also under his emperorship there was a growing unrest in the city of Nemis, and subsequently the entire Nemisian League, which would eventually result in the Nemisian Civil War, an event to would set the realm ablaze.
