The planet Setron housed the Imperial medical laboratory, a laboratory facility. Doctor Royce Hemlock supervised this location, where he conducted experiments. These experiments included taking blood samples from clone cadets who had been moved from Kamino and were being held captive. The facility also served as the place where the slither vine, a biological weapon that was still in the experimental stage, came into being. After the Empire was no longer able to control the slither vines, the laboratory was emptied of all personnel and then obliterated by a Base Delta Zero—specifically, an orbital bombardment—leaving only a destroyed landscape in its wake.
