The Crystal Eyrie was a complex built into and on top of what was previously known as the Azure Mountain.

The Great Uniter held her inter-tribal feast beside the Azure Mountain. She later had the image of a Fire Bird carved into it.

During the collapse of the Human Tribal Federation a fire bird priestess preaching outside the site was stoned by non-human refugees

The Crystal Eyrie was sacked by adherents of the Iron God during the period of the Messiah.
