You'll start this Map trapped between a Tyrant and a Juggernaut. You only need defeat the Juggernaut to proceed, though. After that, you'll fight group after group in a long line until you reach the second encounter with The Proudclad. Before you do, you'll meet Sacrifices for the first time. These foes can use Death, but they drop very nice rewards.
If you return to Eden from Chapter 13, you will appear near the second save point in this area.
