Zonai

The Zonai were an unknown people who constructed several ruins across Hyrule, notably the Zonai Ruins in Faron and Thyphlo in Akkala. Their history, culture and even appearance have been lost to time.

Age of Myth
The only physical remains of the Zonai are a handful of ruins in the Faron and Akkala provinces. Given their heavy use of draconic imagery, it is possible that they worshipped dragons, or were perhaps themselves dragons. According to the Saga of Nohan, the Zonai once spanned much of Hyrule before the return of the Akkalans, and were subject to genocide upon their return as instructed by the Oocca.

The Lizalfos people are speculated to be their descendants, though this is perhaps superstition.
