Are you talking about Kol the Heretic, found outside the Serpent Temple? I don't think you can kill him, but if you do, I'm sure he'll be back later [img]smile.gif[/img] You missed out on a key for a secret room in the Temple, a room that contains a couple of ankhs, some other stuff, and some storyline information.
Or are you talking about H'Thark, the prisoner inside? He was waiting for you to give him his lock picks so he could tell you something... the trick to summoning the serpent, which you will need. Unless you read it in Best Tips already, in which case you don't need him [img]smile.gif[/img]
I'll point out to you that there is a Search option on the forum... so if you get stuck, you can search through old posts for key words and phrases. Some of the answers may be a bit more forthcoming then...
