The table would for a moment activate - a light would shine on the center of the table, and after going in a circle a couple of times dissipated.  An unpleasant erZKZZKZK happened as whatever magic made the table work seemed to a have failed.  A couple of seconds later a pictograph lit up elsewhere on the table - displaying a stone much like the glowing ones resting on the tables edges being placed in the center.  A couple musical notes seemed to surround the table in the blue pictograph.
