Arudo is the capital city of Sairou. It is featured in Byakko Senki as a prevalent location as well as the home of Emperor Nahido. It is not referenced or mentioned in Genbu Kaiden or the original series. The city’s architecture appears to take inspiration from traditional Tibetan design.
The city is enclosed by large decorative walls. Inside there are booming markets with fresh produce, temples, and deep canals that run throughout the capital.On the other side of the largest canal lies the imperial palace. Its design takes notes from both Chinese and Eastern Asian elements with its tall archways, winding corridors, and rock gardens. Also inside the palace is the Hoshinomiko Shrine where the Priestess of Byakko is sent to cleanse her body and spirit.
