Go up and then higher again with another ladder. Go to the higher ground, and go right on the forking. Then go left and take the stairs up. Go through the footbridge and approach the big bridge.
Your task is to rebuild the bridge so to be able to reach the goddess of death. Go towards the metal gate, take the rune on the right. Go back and then right. Take the stairs up and look on the bridge - it's first fragment will be restored.
Go down, use the footbridge and take the other stairs up. Collect the rune and go up. Get to the balcony and look on the bridge - another part will be restored. Go back and a group of foes will attack you in the tower. Teach them respect and proceed. Get back to the bridge.
Enter the bridge and look towards the destroyed passage. Use focus and you'll gain access to the next location. Run there - find another Lorestone. Use the gap in the wall to get to another tower. Some more enemies are waiting there.
After the fight, use the hap in the wall and look on the bridge. You've finally finished rebuilding it. Exit and go up - you will find another Lorestone. Get down, unlock the doors and exit into the bridge. A group of enemies will attack you - defeat them and approach the gate to finally meet the goddess.
