NOTE: If you have not completed the main quest, some spoilers follow.
I am near the end of chapter 7. I have to go meet Arom at the tower to take on the dragon. I already have the key. I can see the ? showing his location on the map, but for the life of me I cannot figure out how to get to it. Can someone please tell me exactly how to get there? I am ready to give up the game, which I am enjoying very much until now.
