I have seen many of those threads where you get to chose some ability / skills that you would like to have in real life, now lets do this a bit diffrent!
Lets say you can bring 1 NPC from world of warcraft to the real world, and yes they would remain themself there, and not become your ''slave''.
You may hope to befriend them or they might kill you (most likely depending on who you pick).
Also it does not matter if they are dead in wow or not.
The choice is yours to make!
