Need help with a good evil Place name

Need a good name for a Vile Place.

My players are about to head into the Wild Run ( a place in my world that effectivily blocks one half the continent from the other due its hefty amounts of mountainous, and boggy terrain.)

And at the center of one dale in particular I want my Crew to stumble upon the ruins of a City filled with a great evil.

I have a running list of good vile names but I have used them all :)

Examples of what I think sound Evil

The Byremog -a large bog in the south of Aryande
Turraz-Ghul- A Fortress of the Death legions of the Black King
Molgiath The Fortress of the Black King Farindul now dorment in the shadows of the Lost Mountain
Ryvvendor- Once a great Dwarven City far beneath the surface of the world Ryvvendor was destroyed by Creatures of darkness, and their foul Gargya (Gargoyles that can turn a victim to stone)
Tuol-Gedar ( The Throne of the Giant Kings)

Yes most names have a Tolkien feel but it is only superficial.
It was a Yuan-Ti Stronghold along time ago but The language they used was an Archaic form of Elven. (IMC Yuan-Ti were responsible for the creation of man, and their blood has been accused as the culprite of Mans Great Betrayal at Tharen-Eiriond)

Also they are responsible for the Sharding of the Gana ( A Large Hoover like Dam) and the subsequent drowning of Rhunedenor ( A smallish city of clerics dedicated to the Goddess Rhune)
