The key facet of the problem this Great Britain country, where several of the Generals dimly recalled a Senshi had been sighted for a while before disappearing not long ago, probably to come here, had set before them.
An entire society of humans that had clawed their way back up to the ability to harness and use magical energies, albeit of the crudest sort, and hidden themselves away from the prying eyes of their mundane, 'muggle' cousins.... and then just stopped.
Britain had provided quite a portfolio of classified information on them with regard to their problem. The society was... offensive. Wrong. Not in that they collected their magical abilities to themselves and did not strive to serve those less fortunate, no, that was simply their right as the priviledged few, to live seperate from the huddled masses. Nor was the expected corruption a true problem, as there was almost always some level of that in any society.
It was the stagnation that was offensive. One of the pictures displaying a shop indicated that it had been around since before 600 B.C., by the humans current calendar.
Over two thousand years! And this society of buffoons were still working magics by waving about sticks and chanting gibberish. The most basic, humble, and amateurish of magecrafts at best. Not a sign of any attempt to work any greater, more elegant magics, or more than the slightest hint of the technological fusions that the unified Earth had once gloried in, that even Mercury had occasionally looked towards for inspiration..! The best in that regard were a few spacial distortions in vehicles, and funny clocks and watches.
