After another day and a half of travel, Carcelon, Kilcif, and Kripp arrive at the edge of the Lake of Shadows. Kilcif's rambunctious behavior makes it obvious that he has broken free of the Matron's domination effect. Carcelon is somewhat surprised that Kilcif didn't desert while the others rested.
The Lake of Shadows is huge, some 60 miles in its longest dimension. The cavern above arches from 50 to 100 feet above the lake, and the lake reaches depthes exceeding 100 feet. The waters of this lake are dark, a darkness so impenetrable that its surface reflects any light back to its source. Smale waves and ripples zigzag across the water, suggesting that something, somewhere, is moving in the lake.
Two islands, a small one close to the shore, and a larger one further out crowned by a sizable building, break the surface of the water nearby.
The tunnel the party was following has opened into the huge cavern. From here, you can enter the lake, fly, or perhaps move parallel to the lake through a series of caves.
Four massive rocks bounce off Carcelon's body, knocking her to the ground and drawing blood (68 points of damage).
Several angry Stone Giants appear to be attacking Carcelon, throwing rocks from places of concealment thirty to ninety feet away.
Kripp knows the Giants live in the nearby caverns and have a treaty with the Kuo-toa (which maybe why they are not attacking Kripp).
