"Additionally, these monsters, as you call them, are a recent development. Previously, only the Seelie were capable of free passage among the realms. The Unseelie arrived on this planet already trapped in a prison. Those few that enjoyed brief paroles did so only at the Seelie Queen's or her High Council's behest."
I'd gotten stuck on a phrase. "Arrived on this planet?" I echoed. I thought about that a minute. "I see. So these monsters are really traveling space aliens. How silly of me not to have figured that out. Can they travel through time, too, Barrens?"
"You didn't think they were natives, did you?" He managed to sound a shade dryer than I had, an accomplishment I hadn't thought possible. "As for the time-traveling aspect, Ms. Lane, that would be a 'no, not right now.' But some of the Seelie used to—those of the four royal houses. Things have happened recently. Inexplicable things. No one knows for certain what is going on, nor even who holds power at the moment, but word is the Fae can no longer sift time. That for the first time in eons they are as trapped in the present as you and I."
