This huge ancient elfish city is all but reclaimed by the forest. Only the immediate area around the tower known as ‘Heart of Sorrow’ is still home to a thousand elves. The tower supposedly contains the ‘Book of Regrets’, an ancient, but constantly changing tome sacred to the elves.
At one time, before the age of man when Kitharra Gaia the Great World Forest covered all the lands, the city of Avarthelar was the elvish capital. Legend has it that it was here that the great betrayal occurred, the elves broke the Gaia Concord and released the seal that started the Second Demon War. During that age, the races of elves was splintered; and by the end of the age the Drow were banished to the Underdark.
The city has also been thrice marked by tragedy during the human-elf wars of this age. The most recent, only 500 years ago marked the fall of the royal house of Galinthrea by the Blackguard Vanalord. With that defeat, the Grey Elves remaining in Thac retreated to Cairthrellon; and the elves of Thac were thereafter ruled by the High Elf house of Aristar, who moved their capital to Kai-Arborus.
