Bayan Oasis is located in the eastern Apiro Desert, south of the Peft Ruins. It was originally founded after the main source moved from Peft to its present location. In order to avoid the mistakes of Peft, the town is designed as an encampment in order to facilitate easy movement if the oasis should move again in the future.
Sunil had a house in the Bayan Oasis, which is where she treated the injured Guilleriga. Ephil was a frequent visitor to the Bayan Oasis, attempting to sell her arrows there.
