Twelve-Winged Dark Seraphim
So something has found someone else. While we don't know who's doing the finding, we can guess who is being found. It's either Demonic Neonate or Zhou Wen, since they are the ones who were moved. Given how Demonic Neonate has a great background within other dimensions and the fact Zhou Wen is not hard to find, I would say that the person was looking for the demonic child.
