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. If you kill Greta in plain sight, leave the city and wait 72 hours. By then the Underworld citizens will be friendly again.(If you agree to kill Greta the option to buy Charon's contract is no longer available.) Upon purchasing Charon's contract, Charon will kill Ahzrukhal by shooting him in the head (blowing it off) and then shooting again after he's dead, claiming he was an evil man. If Ahzrukhal has gone to sleep during this scripted sequence, a bug will prevent Charon from shooting Ahzrukhal.

A good way to kill Greta would be to use the Mister Sandman perk, or kill her during her smoking time (late evening) outside of Underworld under the big skull which leads to the entrance. Using a Stealth Boy (and ensuring you are in fact hidden) while Reverse-Pickpocketing her to drop a live grenade in her pocket is fun to watch too, and gives you the Psychotic Prankster/Pants Exploded achievement.

Killing Ahzrukhal
Killing Ahzrukhal yourself will result in positive karma but cause the surrounding NPCs to attack you, except for Sydney. A way to get the positive karma and not be attacked has been discovered, simply kill Ahzrukhal from a distance (like a magnum headshot), and exit the door immediately followed by waiting for just an hour, then reentering the Ninth Circle will cause the NPCs to not attack you. Variations of this have been attempted with no success. 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 hirable 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.
