Gil'ead keep Eragon Guide

To open the first gate stand on one platform, which is over the door, Brom will stand on the other and the gate will open. Go down to the dungeons, entrance is on the right. Kill the company and go back upstairs. Go through the gate, when Brom draws away attention of the enemy, sneak behind him.

Go on for a few meters and throw down two archers. When you see the next knights wait, until Brom draws away their attention, and then sneak by to go further. Repeat that with the next group. Now you have to climb onto the upper level of the walls. Take out the rock from the wall three times, to create stairs. On the walls there are many warriors, but you don't have to kill them. It's enough to jump over them or roll near by. Move left until you will reach the edge of the wall. Here you can turn down and go right to find the secret egg. Now move towards the huge building and go to the center of the arena, you'll see a movie. You will fall into a cell, but don't panic. Dig a hole in the ground by using the magic and jump down into it. Make a few steps to the next room, where this level ends.
