Human: Generate for a mystical scene inside of a temple with a crystal sphere and a portal. Assistant: 
Windowless walls rise high overhead before curving inward to form a complex ogive vault. Hanging from the central boss from a long, vaalorn chain is a single crystal sphere, glowing brightly. Centered below is a circular crystalline plinth, large enough to serve as an altar, but completely smooth and unmarked. To one side, a shimmering portal stands at an odd angle.
