Perhaps the Jenoine are artificially evolved humans? Perhaps some sort of cult or super secret group that evolved themselves to the point where they are not only immune to conventional physical trauma, but to anti matter (amorphia). When some left Earth, they brought reminders or pets with them-regular humans, the ancestors of Easterners. Also, I'm surprised that amorphia hasn't been compared to anti matter before. The stuff destroys matter when it touches it, creating a flash of light, and a violent detonation. It isn't found naturally, at least not yet. The question is how the Orb channels it to make it safe for non-war use.
