A Tyran observes one of the many buildings on Tyris which is supported by their anti-gravity beams. The science is well-guarded but Tyran engineers can be hired by outworlders -- for a steep price. Problems with the Tyran sun have disrupted the fields briefly, and their engineers are studying the problem. The Conqueror has ordered no further Tyran buildings be constructed on Tarth until the problem is resolved. The media is watching with rabid interest as the situation unfolds.
