Stuck after first prince fight

[Laezyre]

After "winning" the first prince fight, I visited the mage tower and befriended the elves. I won the cave fight with the thief mage(the fake necro fight) and kept his secret from the dwarves. I ran around killing many easy enemies and now can't seem to find any direction. Eric has his huge armies in Greenwort. Nobody will give me a new quest, and all my current quests are in areas that I can't reach anymore.
I can't get into the mine.

What am I missing?
