About

Note: Treasures, monsters, and NPCs are generated randomly, so the information generated is pretty rough on the edges. Its supposed to be more of a guideline.
For use in your game consider the following options: changing or removing encounters, equiping NPCs, treasures listed belong to NPCs (i.e.: the treasure is not just lying around) or is hidden, removing treasure altogether, changing the alignment of NPCs, placing traps on specific locations, etc.
