Be especially careful of those that can fall down from above. Continue down the path ahead and you'll find hollows. Head back up to where the summoner was, and then take the stairs at the end down and around, where you'll find an NPC on the left. There's also a doorway beneath where the summoner was, and to the left you can find a Hidden Blessing on a corpse. If you go down the bridge, you'll find a Large Soul of a Weary Warrior, an Ember, 2 Budding Green Blossoms and 2 Titanite Chunks on corpses. Once the summoner is dead, you'll get a Divine Blessing and a Titanite Chunk. His shades will appear again to try and fire arrows at you, and there is also another shade that he can spawn that is a black knight that will use a Black Knight Greataxe to try and melee attack you. Around the ledge near it, you'll find a ladder that you can climb up to find this large man who summoned the shades attacking you. On the opposite side, there will be a Crystal Lizard. If you continue going down the bridge but stay on the right side, you'll find a ledge that you can drop down from that you can find a Soul of a Crestfallen Kight at the bottom of. Try to time your movements alongside the delays that occur when the shades stop firing at you. In order for you to dodge the arrows, it's best that you use the grave stones along the right side as cover. If you turn around the right corner behind you, you'll find the Ruin Set on a corpse.

As you go down the steps, shades will be summoned that fire arrows at you.

Then light the first bonfire that's up ahead. Once you can control your character after droping down from the Demon Prince fight after the Earthen Peak area, head down to the left and speak to the NPC.
