Twelve-Winged Dark Seraphim
We have several confirmed characters from the third world. Fengling, the antelope, Ark Lady, An Jing and the LIS woman. Unfortunately, we do not fully know the past of all of them. Only An Jing's past is fully known and since this novel has ended, they will remain mysteries unless they're covered elsewhere by the author. The ending is somewhat disappointing, as there is no real sense of closure. I wouldn't say this was one of the best stories I've read, but I did enjoy the ride.
