Tinwael Galéth
The Tinwael Galéth (the Vast Greenwood in the Common Tongue of Sarapadia) is a massive forest spread along the entire northern coast of the continent of Sarapadia. It was originally populated sparsely by some humans and halflings, but elves came at the onset of the Ulon-Zirak from a far away land called Tarisir in Apadia and a tribe of the settlers moved north under the direction of a powerful elven enchantress named Tifira. Over the last millennium, the Tribe of Tifira thrived and settled the entire forest, dividing it into three regions: The Eastern Kingdom, the home of Tifira, and the seat of power at the Capital; the Middle Kingdom, currently under the rule of Nissa; and the Western Kingdom, currently under the rule of Ardaz. References to the Westgate, Southgate, and Eastgate refer to the forest as a whole, but each region has localized gates made to look like other region gates as a sign of fellowship.
Urdai Sinwal and Tinwael Galéth both are largely populated by elves who speak generally intelligible dialects. Some words are just loaned to the other for names which are localized when spoken. The words Sinwal and Tinwael are cognates, from an ancient Apadian elvish *tsinwael, forest, literally bark-home. Thus the common tongue of the Karthus Plains uses "wood" or "bark" with the color descriptors Galéth (green) or Urdai (grey) to form Greenwood and Greybark, respectively.
The Eastern Kingdom
The Eastern Kingdom is the location of the Capital of all of the Tinwael Galéth, but this has been a mere technicality for some 600 years, with each region keeping its own business and choosing its own leadership. The Capital remains the home of the Enchantress of the Portals, and all enchantresses have ever been born there since its founding and the construction of the first Portal at the Northern Sea Cave. The government has typically been formed of the Enchantress as Queen, or a close relative, and then she married an arranged suitor from the political realm of the Eastern Kingdom. The most recent King and Queen, Galen and Marah, were murdered 70 years ago, leaving a Steward, Pertwyn, in executive control of the Eastern Kingdom until Rheya reclaims her throne.
The Eastern Kingdom has been silent and in some sort of seclusion over the last 70 years, and only recently has contact been made to discover the greatly reduced and sequestered population.
The Middle Kingdom
The Middle Kingdom is home to the more nature-attuned and less civics-attuned Children of Tifira's Tribe. They live attuned with nature in an autonomous collective loosely ruled by Queen Nissa currently. There is a mirror of the positions in government there as there is at the Capital, but they are volunteer positions awarded on merit rather than related to bloodline. The seat of power for the Middle Kingdom is Kyrfor, home to the great tree Ülamalora.
The Western Kingdom
The Western Kingdom is a militaristic culture of warrior-kings. The current King Ardaz was chosen by majority among the current wariors of the kingdom. The Western Edge troops are the elite troops warding the western edge of the Tinwael Galéth and are on excellent social terms with the Northmen of Grünvik.
