Notes of Caution:

1. Make sure that if you are doing a cave and make the room lit with light, put a description in the room saying there is a torch or something providing a light. This would make more sense in a dark tunnel or cave. Otherwise, make it DARK with the DARK FLAG.
2. Make sure that if you DO NOT want certain mobs roaming around in other parts of your zone, that you use the NO_MOB flag. Put the NO_MOB flag where you would cut off the roaming mobs from attempting to leave. As you will see when you get your zone on testmud, mob flow can be quite tricky.
3. Don't forget to use the INDOORS flag when it is appropriate, or you will be getting outside weather in small huts-- that is not realistic.
