Timber Vale
Here is the first zoomed in map I've done for Athas East. The region is known as Timber Vale. Below is a brief description of this region:
Anboeg is this regions Tyr for the most part. Most adventures would start from that city, while adventure locations of note would be The Dustglow (old Green Age lighthouse) or Relugor (an old dwarven hold that still stands relatively intact to this day). Muvenor and Dopt are vital to the regions defense from the wilder regions beyond the Timber Vale.
Each of the lesser cities are ruled by a sorcerer/priest known as a solon and the vale is loosely aligned together against forces outside of the vale. Anboeg's traditional ruler was usually a sorcerer/priest/psion that is both sovereign & chancellor, known as the Dragon Emperor. However, the last Dragon Empire died 300 years ago, as he didn't survive the transition to becoming a dragon. In his place, a new ruler took power at the request of the solons, a man named Julro Mar'ihr whose official title, at the time, was simply Magnate. After he took control of power in the vale, with the solons as his advisors, his title change to Dragon Regent. This title has been passed down through the last three hundred years, sometimes through hereditary means, sometimes through the will of the solons.
The current Dragon Regent is again a member of the noble Mar'ihr family, which has remained prominent in the vale through the centuries. Hilrao Mar'ihr is only the sixth Mar'ihr that has held the title and the first in the family appointed to the position by the solons in nearly 140 years. Note that the Dragon Regent has real little power outside the city of Anboeg. The solons rule the rest of the vale. The solons of today are the same solons of 300 years ago and are all on the path towards becoming full dragons. This knowledge is widespread through the vale and the solons are greatly feared, as a result.
Dragon Regent Hilrao is the best chance for change in the vale since the time of his ancestor who first took the title. He is a strong-willed sorcerer/psion who is planning to become an advanced being as well, but an avangion, not a dragon. He has gone to great lengths to ensure that the solons don't discover his plans and he plays the part of the dull-witted Dragon Regent very well. However, he knows he is playing a *very* dangerous game with the solons and that eventually there will be civil war in the vale.
Only time will tell who survives to decide the vale's future...
