Lake Dark

Natural Feature

The largest body of fresh water within the nation, Lake Dark is glacially fed from the Mror Holds. While the upper reaches of the water—where people boat, fish, and swim—are perfectly ordinary, the depths contain a manifest zone connected to Dolurrh. Local criminals know better than to hide bodies in the lake bottom, as those who die an unjust death will almost certainly return as a revenant if their bodies enter the manifest zone. The lake is deep enough that little light penetrates the depths, and divination magic has failed to provide a definitive answer to what lies at the bottom of the lake and rumors abound. Roll or choose from the Lake Bottom Rumors table for local color.

The pitch-black waters of Lake Dark shimmer in the farmland in eastern Karrnath. Fed by the cold runoff of the Iron River, Lake Dark is a large body of mist-shrouded water that collects in a depression in the fields between the Icetop Mountains and the Talenta Plains. The small towns of Lakeside and Irontown flank Lake Dark, and smaller farming communities encircle it with their various kinds of crops. Many believe that spirits haunt Lake Dark, and that the pitch-black waters provide a pathway to Dolurrh, a location from which the living can sometimes speak with the dead. Lake Dark is a manifest zone connected to the realm of the dead, and spells related to necromancy have greater power when cast in proximity to its dark, restless waters.

Operation Leviathan

Source: Five Nations

Once such endeavor, known as Operation Leviathan, involves Emerald Claw cells across Khorvaire. Most members of the Order know that they’re supposed to acquire as many Khyber dragonshards as possible for something called “Operation Leviathan.” But Emerald Claw leaders know more: The Order is gathering hundreds of Khyber dragonshards to draw forth from Lake Dark a monster of unspeakable power, then bind it to do Vol’s will. Not even the Emerald Claw clerics who will perform the ritual know exactly what the monster in the bottom of the lake is. Ancient texts speak of it as being the equal of any army, capable of destroying entire cities and cutting a swath of destruction across the landscape.

Getting PCs Involved: Most Khyber dragonshards are still in the depths of Khyber, of course, so PCs who travel deep underground can meet Emerald Claw agents trying to mine dragonshards. But mining isn’t an area of expertise for the Emerald Claw; they’d rather have others do the work for them. Emerald Claw agents try to steal any Khyber dragonshards that reach the surface world—whether they’re in the hands of other governments, dragonmarked houses, or the PCs. The Emerald Claw is also seizing control of mining operations and enslaving the miners to get more Khyber dragonshards.

If the PCs don’t get involved in preventing the Emerald Claw from gaining the necessary Khyber dragonshards, they have two other chances to stop Operation Leviathan. They can disrupt the nightlong ritual that will call forth the creature from Lake Dark. And high-level PCs might be able to defeat the creature once it emerges from the lake, ready to do Vol’s bidding.
