Research on this piece of cosmic debris had yet to make any breakthroughs, though two things had been confirmed so far: first, it undoubtedly came from another universe. The entire asteroid belt had jumped into this space, propelled by the fragments of the Star Ring, and the smuggled goods mixed within couldn't possibly be products of our own universe. Second, its creators were part of a civilization strikingly similar to Earth's—naturally, the former was infinitely more advanced than the latter.
It had been designed for human use and control, featuring seats with backrests suited to upright vertebrates and visual display terminals. The cockpit's airtightness led us to believe that its previous owners definitely needed to breathe, which... ahem, the diligent scientists even deduced that the users had ten fingers based on the layout of the keys on the aircraft's control panel—I have no idea how they came up with that conclusion.
