From the introduction:
This offering has a series of maps I drew playing around with a new mapping style. The title, Three Rooms and a Tunnel, are exactly what you get. They are only connected if you want them to be. I wrote them as separate entities. I like the idea of throwing in a single room into the mix. If nothing else maybe there is something within that strikes your fancy and you can plunder it for an idea. I really like the idea of harvesting creatures for magical components that are used for various things. An infinite amount of options could be had when you give them to the players. In one room, a fire elemental heart is found, a diamond that shimmers with the colors of fire. First off, that is cool enough. Second, it can enchant a weapon to do fire damage.
