Ahzrukhal

Ahzrukhal is the bartender who stays in The Ninth Circle in the Underworld, which is located in the Museum of History.

Initially, Ahzrukhal only offers alcohol, but through dialogue options (no speech check) you can convince him to sell you drugs like Buffout and Jet.

Hacking Ahzrukhal's computer will reveal some of his misdeeds, including planning to steal medicine from the doctor to sell at his bar.

Unmarked quest: Hired Help
Ahzrukhal has the contract for Charon, which you can purchase for 2,000 caps (or 1,000 if your barter is 50 or higher). You also will have the option to kill Greta to obtain the contract.

See Hired Help for more info.

Killing Ahzrukhal
Killing Ahzrukhal yourself will result in positive karma but will cause the surrounding NPCs to attack you, except for Sydney, who will wander around in the bar if you have completed the quest Stealing Independence. One way to get positive karma and not be attacked is to simply kill Ahzrukhal from a distance (by using a magnum or sniper for a head shot), and exit the door waiting one hour immediately after leaving, then re-entering the Ninth Circle will cause the NPCs to not attack you. His body will have a key to unlock his fridge where, strangely, he keeps stimpacks and about 200 caps (as opposed to all of that in the safe?). Charon will not be able to be hired this way, he will still talk to you as if Ahzrukhal was still alive. The best way to kill him is to let Charon kill him when you obtain him as a companion.

Some of the customers at The Ninth Circle will mope about his death (if Charon killed him.)

As you know, Ahzrukhal gives you good Karma for killing him. Killing him also loses your chance of having Charon as a follower. You can get around this (To do this requires a couple items: Silenced 10mm pistol and a Stealth Boy) by buying your way to Charon's contract (or, in other cases, killing your way). Tell Charon you have his contract. As he's walking over to kill Ahzrukhal, activate the Stealth Boy, pull out the Silenced 10mm pistol. Jump behind the counter, and, right after Charon has his Shotgun out, go into VATS and go to Ahzrukhal's head and fire a couple times. If done right, you will Sneak Attack Ahzrukhal and he will die from the shots, giving you the good Karma. Charon will believe that he killed him himself, and will talk to you after shooting Ahzrukhal's body.

It is not known whether or not you actually do need the Stealth Boy or the Silenced 10mm pistol but it would probably be wise to have them just in case. Note, it has been reported that this scheme will work without the Stealth Boy - but not all the time.

Stealth Boy not necessary (Confirmed to work on PS3 version) as long as the player is out of the line of sight of everyone but Charon and Ahzrukhal. The following steps will produce an outcome where the player receives karma and experience for killing Ahzrukhal, while leaving Charon with the impression that he is responsible for his ex-master's death.
 * 1) Wait until only you, Charon, and Ahzrukhal are in the room.
 * 2) Save your game in case you mess the next part up.
 * 3) Equip something powerful and (ideally) accurate (scoped .44 mag works great).
 * 4) Tell Charon you are his new boss.
 * 5) Position yourself so that you have a clear view of Ahzrukhal but are not visible from the adjoining room (as Charon moves in for the kill).
 * 6) Let Charon get behind the bar and start his dialogue with Ahzrukhal.
 * 7) As soon as Charon starts to raise his gun, enter VATS and blow Ahzrukhal away.

If timed correctly, upon exiting VATS Charon will shoot Ahzrukhal and think that he killed him. If, instead, Charon becomes hostile and starts shooting you, it means you didn't wait long enough to pop Ahzrukhal. Load and try again. I also experienced a bug where Charon continues shooting at Ahzrukhal for some time after he is dead (7 or 8 shots when I did it). However, this did not affect the outcome--Charon eventually stopped shooting and pronounced Ahzrukhal dead. Be sure to grab Ahzrukhal's key and loot all his stuff from the fridge. The wall safe can be opened by hacking the Very Easy terminal on the counter.

Bugs
Sometimes when you inform Charon that you have obtained his contract he will walk up to Ahzrukhal and do nothing. This will prevent you from talking to both Charon and Ahzrukhal. (confirmed on PS3)
