That generator sabotage wasn't a ghost. It was a slime. A ditto, I think... Nothing else I know of could go incorporeal to get downstairs into the generator room, yet be able to cut the wires without a tool! Thing is, we don't have any registered dittos in the Academy. Can anyone recall seeing one somewhere before the storm? Meeting one in the city maybe?
