I knew I wanted to try my hand at painting red sandstone cliffs, and looked around the internet for some references. There were a few shots of sandstone cliffs thrown into orange and purple relief due to the photos being taken somewhere around sunset (or perhaps sunrise) that inspired the colors of this image.
In Tamriel Rebuilt, Roth Roryn is a landscape of orange cliffs. It borders the Deshaan Plains to the south, which in Tamriel Rebuilt, are actual plains as the old name dictates instead of marshlands as they are seen in Elder Scrolls Online. The purple, gray, and green coloring of the Deshaan plains also comes from concept art of Tamriel Rebuilt, serving as the main color palette for this zone.
