Jason just told me to kill the nightkin in the basemant and then the ghouls would leave. I then met Davision who I agreed to help find stealthboys. He gave me a key I then killed Harland. By agreeing to help Davision and killing Harland I thought the nightkin would leave me alone, the problem is Im looking for stealthboys for Davison and the nightkin but the nightkin are killing me. Whats the point in helping the nightkin when they kill me when Im trying to get stealth boys for their leader. I have no idea how to find stealth boys or how to kill the nightkin. Im in basemant running around in circles. Any advice would be appreciated. I feel like going back and killing Davision for the sheer hell of it . The only reason I agreed to help him is that I thought the nightkin would leave without me having to drive them out.

Why kill Harland ?

All the other Night kin are hostile..(.this is part of the game., nothing you can do about it )....except Davison.

Just talk to Harland...pop a stealth boy and find his companion....leave your companions in the room with Harland.
As long as you are crouching the other Nightkin can't see you..just sneak by them. ( With Stealthboy )
Find Harlands friend....come back and report.....he'll let you look at the computer terminal ( Up where he is at..this will tell you about the Stealthboys ) and then go back to Davison....quest done !

Everybody lives....

If you kill too many Nightkin.....Davison will become hostile regardless.

Thanks. I guess ill crouch past nightkin, have no idea how to kill them and return stealthboys to Davison. I killed Harland because after agreeing to help him I advanced to far into his room and he began shooting.

Just stop at the entrance to Harlands room...if you go further into it or attempt to climb the stairs he will open fire. ( This is intended )

His companion is the other way anyway..just leave your companions by the door in Harlands room..sneak back to the jail cells...take the jail key off the desk..and go down the jail room stairs through a couple of locked doors and find Harlands companion.
Just follow the arrow....

Once you tell Harland the bad news he leaves and you can head up to where he just was...there is a terminal up there with the Stealthboy shipping invoice on it.

If you already killed Harland and don't want to reload an earlier save..just go up to where he was and use the terminal...no sneaking required. Just read the reports and head back to Davison.

Thanks. Ive already killed Harland so will just head back to the terminal and read the reports.

Davidson is always hostile to me. He babbles something about "Antler says attack" or somesuch, then comes at me. I always end up killing him.

I currently have this quest still pending, and am wondering if it's even possible to get the opportunity to talk to Davidson since to reach hm you have to kill a bunch of Nightkin anyway and the Wiki says that doing that will make him auto-hostile.

In case it matters it should be noted that my character has a low Sneak skill at this time, although I do have a couple of Stealthboys stocked up in a crate in Goodsprings in case I need them.

Do I have to sneak past the Nightkin just inside the basemant entrance, or can I blow them away and still have the chance to talk to Davidson? The Wiki is unclear on this point, and merely states "If you kill all the Nightkin in the basemant Davidson will automatically be hostile". (paraphrased a bit)

Some times Davidson would hear you fighting on the other side of the basemant, but not when you fighting on the corridor leading to his room........

Just sneak right by with a Stealthboy....there are a couple upstairs in a safe and one on a Brotherhood body when you first come up the stairs to go in.

Sometimes there are no Nightkin between the entrance and Davison...so no fight. ( and between Davison and Harland )

But this is a Stealthboy mission...just use crouch and a Stealthboy and nobody will see you,,,just stop and wait while patrolling Nightkin pass you in the hall ( They might sense you if your moving right next to them ) but sitting still they can't see you.

If you kill too many Nightkin Davison is hostile ( you can kill the jailer though )...or if you even come close to the skull.

Stay away from the skull...even to bump it is an invitation to a Davison attack.

Just stay away from it until Davison picks it up....don't even go to the other side of the room Davison is in until the quest is over...!!!! Even breathing hard on it will set him off..

In some of my games Davidson talks to me, although I've killed some other nightkin before I met him. In my current game he won't talk at all but attacks right away.
In one other game he talked to me, I agreed to help, I talked to Harlan, did all the stuff, returned to Davidson and now he attacked me without listening first.

In the games, in which he talked to me both times and finally left peacefully, I killed all other nightkin, too. So the entire scenario looks a bit chaotic for me.

In both situations - talk or fight - I was standing near the door, so I didn't come close to the skull and didn't touch it.

Anyway: I've not seen consequences, neither when he left for good nor when I killed him. So does it even matter?

It helps to actually talk to people and pay attention. Davison says that the rest of his Nightkin aren't in possession of their faculties and will continue to attack you.

The point of working with Davison is it means you don't have to fight all of the Nightkin. Just the ones you encounter - Davison. There's usually at least 3 Nightkin I don't have to kill because of taking that route.

If you killed Harlan, then you shouldn't even need to explore the rest of the area. As Davison says, what he's looking for is in the room for Harlan.

I think if you kill the Jail keeper Davison would be hostile to you.

It really depends if you rather fight the Nightkin or bully the Ghoul.

You can appease both, I have twice. Maybe if you kill more than two Nightkin before talking to Davison, that makes him hostile. Or it could be a bug. I always go straight to him, though.
