In the area after the airship crash is a glacier that has a bunch of doors that are frozen shut.I got the holy symbol to open them from the frozen dude but ther is one door that isnt affected (second one up from the bottem in the lower left corner) .there is another door that wont open becouse something is on the other side of it preventing me from opening it.I am totally lost at this point.PLEASE.PLEASE help me...

Um.......you have missed area near the bottom right corner that leads you round to the other side of the door. Watch out for the trolls.

go up and kill the queen remorhaz and turn right kill the sorcerors, beware of the golem. Head down from there and kill the sleeping remorhaz.
