Wintershiven

"As the rot of cultural and social decay started to penetrate the Great Kingdom, many of the more devout and outspoken followers of the god Pholtus withdrew from the increasingly corrupt core of the land. Some of these settled between the Rakers mountain range and the Yol River. Around 356 CY (Common Year), when Nyrond declared its independence from the Great Kindgom, so did these religious refugees. Thus, the Theocracy of Pale was formed.

Its original capital was called Wintershiven, but it was a good twenty leagues south of the city that now bears its name. When the troops of Nyrond moved in and subjugated the Pale, the entire capital was destroyed in a tragic fire. After the Treaty of Rel Mord, the Nyrondese troops withdrew and left the Pale to its independence (the date is still celebrated as a national festival, 'The Emancipation'). A new capital was built and was graced with the name of the old."
