I've read Most BYOND Forums and the Guide None of them told me for a Talking NPC, and Lets say I had a Cave and Only I may enter it, The code would have somehting with ckey, No?
I don't see how a "Talking NPC" and a "Cave with an owner" are related.

Which one would you like help with?
turf
Entered(mob/M)
if(M.key == "Avarie.David1")
return ..()
mob
NPC
verb
Talk()
set src in oview(1)
usr<<"Hey [usr]"

Can you throw more detail into the question? Try laying out for us exactly what you're trying to do, in depth. That's important because you have to do the exact same thing when programming.

As Gooseheaded said, I don't really understand how these two concepts are related. You must have something in mind that isn't coming across, but if you can give us more to go on we can work with you.
