I am standing in front of the barrier, killed all the bad guys and found one!! notice saying I should use this spell on the barrier. Iread the solution was "sesam", but I did not find any clues how the find "seam" and how to use it. Desperate, thanx for any help----------------

try to open the door, if you have the spell to open it up then an option will come in the dialogue to read from the spell

You can also get to him by using the teleport spell in the north west part of the map.

You need to read a spell called "Orders" from your inventory while standing in front of the blue barrier:

"Speak this spell before the barrier of the Winter King. Its incantations will call the spirits of the Realm of Faery away from their stations, andyou may pass freely."

One of the immculate groups drops this spell. I cant remember which group it was though, there is one by a fire camp near the entrance and there is a big group at the entrance of the elemental forge.
