The group makes good time through the rest of Drooam, there is nothing that threatens you or even all that interesting. You reach the Blackwater River and the border of the Shadow Marches, the land having become softer as you got closer here. The map guides you to a small, rickety looking crossing, but the wooden structure holds up to any probes. Passing over the dark water, you touch down on the spongy surface, which gradually slopes downwards, leading into calf-deep water for as far as the eye can see ahead of you, Cypress trees protruding from the water, which at many places has a layer of duckweed on the surface, the green plants hiding the water from view. Almost immediately upon entering the swamp you are set upon by deer flies, their knife-like mandibles pierce your skin and the painful bites bleed.
The map has a path that appears to do its best to stick to solid ground, although it appears to be impossible in the current situation. As you move along the marsh, you see the remains of a great beast approximately 50' in the water, large bones sticking out of the water.

There looks like a large shape lurking under the water, just to the south of land you're on.

You think you see a mound of debris move on the island to the northeast

You see many small insects gathering along the trees of the central island, mandibles clicking together[/sblock]
