I just finished killing the oracle that Granma sent me to after getting the third map piece. A gnome came up and said the king of Alfheim (the Fae city where no one likes you) wants to meet me secretly. I cannot figure out how to get into the Alfheim palace though... I can currently only go to two places: Alfheim and Asgard. Both are pretty limited with what I can do. I have talked to everyone in both cities and came up with nothing. I noticed a couple doors where locked or guarded in Alfheim and can find no way past. I give up. Help.
