I made a few assertions in my Roget Parrion scene that should be revealed here.
The Centre for Dimensional Research is a large complex resting on its own island. There are some underground levels, and several stories topside; within it mostly are engineers, mechanics, researchers and analysts who dissect information gathered from research. Four notable room exists -- the Dispatch Chamber, the Observation Deck, the Royal Prison, and the Primary Construct. The Dispatch Chamber contains a large Gate frame that gathers coordinates sent from the Construct and allows travel of large groups of people between dimensions (or time, if such a thing was needed). The Observation Deck, using spectator magic, is capable of monitoring a target dimension in a variety of ways, even perhaps projecting the world around a viewer (similar to Quantum Leap or the Holodeck of Star Trek). The Royal Prison is, in actuality, a branch of the REAL royal prison on the main continent, and is equipped with cutting edge equipment for research done on dimensional prisoners. Lastly, the Primary Construct, by far the most important area of the Centre, contains three vital machines -- firstly, the locator rests there, on which an object is placed and its quantum signatures examined for copies in other dimensions. Secondly, a viewing port using spectator magic exists to its left. Lastly, on the locator's right is a Gate frame that can accomodate about two people, used for immediate "service" access to a dimension if something goes awry and an official dispatch cannot be arranged.
Finally, I've written that dimensions are destroyed after full research is conducted by the releasing of the Frozen Flame within the target dimension to lock level D (a sensitive level, suggested by Chronopolis's usage of it in the Time Crash). Once that is done, a directive is established via the Flame directly to Lavos that forces him to erupt. Done in prehistoric time, this ensures that humanity will never come to pass, and the slate is wiped clean of ZEALian interference and its effects.
