Caerbannog is one of the lost ancient cities of the old Dragonborn Empire. In his personal journal, King Harkano writes that he and his daughter fled to Caerbannog with a dragon egg after the fall of Sunwyn. A healer named Nera was said to reside in the city and she possessed an artifact that could prove to be a powerful weapon against the undead usurper Fyrus.
Today, Caerbannog sits in ruins. Orcs fight each other for control of the old city and whatever loot they can find.
