The eastern frontier is where King Braddock is currently pushing everyone to go; he hopes that by pushing out past the eastern mountains, and through the Free Frontier, he can create a buffer from the always wild monstrous bands (which are rumored to be rekindling the Great Alliance), while providing him more territory (e.g. taxes). It would also help ease the problems of overpopulation which people are citing in the Western Kingdom; the Western Kingdom has a population density of about 1 person every 3 square miles, which by the standards of most people in this time and area, is quite dense. They want more open land, for farming, for hunting, and for the occasional black wizard's tower with strange experiments and all. Adventuring bands and the Royal Merchant Company, the private concern of Lord Earl Dunnigan (King Braddock's cousin), constantly lead expeditions into the frontier. The Church also continues to send expeditions into the wild country. Some of them do it for King and Country, some for God, some for Glory and some simply for Money. Either way, the demihumans are starting to pour out of the eastern mountains in droves, and the monstrous races aren't about to take it lying down.
