I mean when a new user first joins and logs in, they find a NPC standing next to where they started . They click on him, say hello, and he might say back something like:
\"Oh, friend traveller. I seem to have lost my way around. I had a compass but I must have dropped it. How will I find my way home now? Can you please go to Trogg\'s Emporium on the far side of town next to the great temple and buy me a new one? Here\'s $10 for it and your troubles.\"
Then, you go and buy the compass and return. The NPC then says:
\"Oh thank you friend, but I found my compass. It was in my pocket all the time. I\'ll forget my own head next time! Why don\'t you keep that one? Perhaps we\'ll talk again in the future.\"
So you\'re introduced to talking to the NPC\'s in order to get information - a quest, information about how to get around, where to look for things, etc. Plus you get your compass.
