This magnificent campaing was developed by Mr. Rich Baker and Mr. Colin McComb.
What happens to a lair when brave adventurers enter? they talk, use their intellectual and their diplomatic abilities, a lot of times they fight the irrational enemies, they work together, bleeding or even they die when they confront furiously hordes of minions. But the initial question is not yet answered.
Imagine if that lair is near a population, people with a regent they obbey. Furthermore, even more; if an adventurer becomes a noblemen with the regency of a great kingdom?
What happens if another character confront the ideals of the other character?... also if both have people, army, and social structures of they own?
Well all these things are talked in this campaign setting. You can go to the deadliest lairs of the knowed or the unknown world, leading armies to fight the forces of the adversaries. Its a warfare of roleplay and entertainment, a joy of entusiastic reunions of well roleplay, but it becomes better if you as a DM are going prepared and know something about the players you are gaming with.
For that reason in the new Dungeon Master's Books you become the well prepared contemporary bard that gives entertainment to your folks and became the Game Master of this hobby.
For those things I begun to write my own adventures and ideas only based in this game setting that I really can call the most complete campaign setting Writen by the splendid and brilliant people I already mention in my first words: Mr. Baker and Mr. McComb with all the help of his fellow friends they mention in their books.
