where you fight the fourth boss, Saurfang you turn around looking out. While looking out have a mage or priest slowfall / levitate you (i was a mage so i slowfalled myself) mounted up and jumped off the ledge at full speed. you will land outside of the area and allows you to run around. Theres really no point to this except being somewhere your not meant to be. I thought this was kinda cool and would share. I am sorry but i have no pictures of this, but its really easy to do
