The Ilumnos Series
This massive machine, located in the Ilumnos Building, utilizes a strange technology that is based on light and disc-shaped color crystals to transport its operators to another world or dimension. A beam of light is sent up a long glass tube in the exact center of the building. If color crystals are placed into the machine they can be put into the tube, adding their color to the light. The end color comes out of the glass tube and hits a large oval crystal which mysteriously hovers just below the top of the glass dome. When the light hits this crystal it glows brilliantly sending the selected color light out of the building through the glass dome. Users of this machine will find that they are still in the Ilumnos Building but that it may have some structural changes, such as different doors or a new staircase, because they are not even technically in the same building anymore, but in a very similar building in an entirely new world.
