This is a fun trick to pull in the lowbie towns. Use a priest's Mind Control power on a town NPC and order him to follow you. Then start to lead him outside of town. Once the Mind Control wears off, have another player root that NPC, heal, then Mind Control again. By rotating those powers you'll be able to lead your hapless villager anywhere in the world you'd like. So take him to the middle of nowhere and lock him in so he can't just wander back.

Be sure to grab crucial quest NPCs, and go and watch the chaos when the guard captain the newbies were gathering rat tails for is nowhere to be found.
