The Border Kingdoms
The Border Kingdoms are little more than names on a map to most folk in the Heartlands of Faerûn. Only a few sages and well-traveled merchants know anything useful about them, thanks to their ever-changing nature, and travel there being hampered by incessant Borderer wars with each other and land-hungry satraps of Calimshan.
According to the sage Meriadas of Westgate: "The Border Kingdoms are the most favored destination for adventurers who want to proudly and boldly conquer a realm or establish their own new kingdom. Lords, counts, dukes, kings and emperors rise, proclaim themselves, and are swept away with the speed and regularity of waves crashing upon a shore. What comes to our ears… are a stream of amusing or colorful little tales of their most daring, disastrous, or funny deeds.
“Few folk go there except those who want to carve out a place for themselves with a sword…. Borders and even the names of the realms they define change with each passing month and even tenday; there is no such thing as an accurate history or even map of the Border Kingdoms (which are named thus) because they stand in the way of Calishite expansion, their turmoil and stubborn strength defining the eastern border of that proud realm… south of the Lake of Steam… the Border Kingdoms spread east and south to take in all the lands drained by the River Scelptar as far as the Shieldmaidens (the hills at the western end of the Firesteap Mountains, just east of The Duskwood) and the rising land that defines the northern edge of the vast rolling grasslands known as The Shaar.”
If you would travel there, Meriadas adds: “Take strong spells, trusty friends, and sharp swords, and you may live long enough to have a brief look around.”
