The Nomad Chronicles

I am standing on the landing pad at near the top of the Temple of Nothing. I float up above the roof. The stone roof opens up to the sky, and a golden mechanical device, the SunDisk appears. I slam a staff with a globe made of circles at the top into the device. The globe spins, and the SunDisk which is a type of concave mirror, spins. Then, I point the Mirror at Urth. I see dreamers begin to float up the beam of light.
