I was thinking that the way to connect the happenings with the Ranger group with the Royal group would be either a messenger from their side could go to the kingdom to report the happenings, or a royal from the Royal group could go to Galuntrug (Alistair might be the prime suspect for this; maybe Lethonel and Rida, if the scholars would say that the Deiran was last seen to the north, somewhere near the Galuntrug).

Pretty much, we can't keep the events isolated from one another.  Maybe it is time for the Rangers to meet the Royals?  Hahaha XD  This could also spark the first instances of combat between the two factions.
