You will now find yourself outside again, known as the Maw. Follow the path down and go through another door, clear the room, and continue through the next door. At the end, jump down, fight off some skeletons, and go through the door. Use the shadow key on the locked door, and follow the path straight ahead.
Go back the second bridge and use the wooden beam and ledges to get across the first bridge. Go over the second bridge, and open the chest for a shadow key. Shoot one in order to explode the one on the switch, and the second bridge will close. Go across the first bridge, and before the second bridge, turn around to see your trail of bombs. Before crossing the first bridge, use Deathgrip on a shadowbomb, and form a trail of bombs from the spawner to the switch on the wall. You will come to an area with two bridges, with one needing to be extended. Once they are all cleared out, head through the now open east door. You'll end up in a circular arena filled with Skeletal Warriors. Go through the door, and once in the next room, ignore the locked door and head through the north door. To get across the gap, just wallrun and jump near the end of your wallrun. On the lower level, stand on the pressure plate leading to the east corridor which will remove the gates blocking your way for a short time. Once at the top, find the hole in the floor and jump down.
Once you reach some wall vines, grab onto them, perform a 180 leap, and use a series of Deathgrip targets to climb the wall. Once inside, use Deathgrip to get across the gap in the floor. Welcome to The Breach, a short mini-dungeon. Cross the bridge and follow the waypoint on your map until you find the Breach. Before crossing the bridge, look to the left to find Relic of Etu-Goth #1. Head south through the Craglands to get to Leviathan’s Gorge. After that we are given a new quest: track down the Lord of Bones, and a new collection side quest: The Lost Relics. After a lengthy cutscene, we have a chat with our new merchant buddy.
