Uhm, not really Kiya. The Imps have always been in that world. One of the books even describes the supposed battle between a demon (I'll look up name when I get home) and Raan through which first the Imps are created then the Raan.
Then there are the books on how to select/train/treat your imp.
And the novel that is included in the pre-orders indicates that imps have been around so long that the Raan don't even notice them any more when they scurry around doing the tasks that the Raan expect them to do (The one reason that Damien could steal the crystal).
