There is a very strange NPC, you can come across very early on in Bloodborne, called Eileen the Crow. She is a friendly hunter of hunters hidden in a passageway close to the entrance into the sewers in Central Yharnam.
We’ll explain how to find Eileen the Crow in Central Yharnam and activate her for Tomb of Odeon and other locations. Just talking to her when you first meet her will give you two rewards: 4x Bold Hunter’s Mark and Shake Off Cape Gesture. If you thought that is all there is to this NPC you are gravely mistaken. There are several things that can happen in a single playthrough and the way it all plays out will affect what rewards and unlocks you receive. If you are interested in what weapons, items and gestures you can potentially receive from interactions with this mysterious hunter of hunter read on.
Eileen the Crow Central Yharnam location
Eileen can first be encountered when you get to the entrance into the sewer area of Central Yharnam. From the spawn point go left (that is a shortcut you probably unlocked to get to Cleric Beast boss) and through the house (don’t go upstairs). Pass the area with dogs in cages (you will probably have to fight a couple) and continue straight. You will pass by the house with senior citizens requesting help to your left and you are at the entrance to the sewers. Go right from the entrance and destroy some barrels and coffins to reveal a secret entrance. Once inside that room go along the right hand wall and destroy additional crates to reveal another secret passageway. At the end you will see Eileen. Talk to her twice to get rewards. You do not have to have killed any bosses by now and if she is not there you might be a victim of an in-game bug.Here’s a video guide for her first location:

You will have to kill Cleric Beast and Father Gascoigne and reach Cathedral Yard zone before the next time you are able to meet Eileen. Once in Cathedral Yard you will have to get a key called Hunter Chief Emblem, that can be purchased in Hunter’s Dream from normal vendor there for 10000 Blood Echoes.

If she dies (or you kill her on purpose) you will be able to loot her body and pick up Crow Hunter Badge. This key unlocks Blade of Mercy weapon that you can purchase for 40000 at Hunter’s Dream vendor. You also unlock Crowfeather Set armor at the same vendor consisting of the following items: Beak Mask for 10000, Crowfeather Garb for 18000, Crowfeather Manchettes and Trousers for 8000 each. If you kill the hunter as well you will be able to loot the Heir rune from him.

If you manage to defeat the hunter and Eileen lives she will reward you with the Approval Gesture and you can loot the Heir rune from the defeated hunter. You will also be able to meet her one more time.
