Zradnirras is a ruined city along the Myrfrus River in eastern Iobaria. Once a powerful city for both the cyclopes of Koloran and the humans of Iobaria, housing the legendary Zradnirri Arcolleges, the city is now a ruin plagued by goblins and kobolds who worship a family clutch of dragons hunting in both the city and nearby Deeprun Crevasse for prey.1
