I think it is a bad idea to make a move on Ziflin at the moment. The Dragon is still pissed and sneaking into it's lair right now would definitely see it turn out bad independent of the mystery creature from Mhonar that moved in.
So take assault Rhyn, fortify Ziflin entrances and talk to dragon. Also see about taking Mhonar since it appear to be empty and will link up the hold independent of the caldera.
