The Heroes of Westfall
Vor Rukoth is an ancient Bael Turathi city located on Blackrock Island.
It is a dangerous place, but adventurers by the dozen go in to loot its treasure, and very few eventually come back out.
Vor Rukoth was once a jewel of the Bael Turathi empire, but the war with the Dragonborn empire eventually destroyed the city when Dhuryan Flamebrow and his soldiers marched on the city and all of the soldiers on both sides were inexplicably slaughtered by a band of devils. No one knows where the devils came from, but the battle ultimately spelled doom for both empires.
