- Rocasta is based off the city of Rochester, in New York State
- Unlike many other towns, Rocasta has no city gates, rather buildings that creep up further into town.
- While Maven and Mare visited Rocasta, as part of his coronation tour, an attack on Corvium took place.
- Many Silvers injured in this attack were taken to Rocasta.
