Etna
Looking carefully as you move slowly forward, at first you don't see much more than normal animal traffic. However, soon you begin to spy small signs of something different. Bits of animal here, breaks of reeds and bushes there. Soon they become more noticeable, leading you on a slowly winding route toward the large bend in the river.
At one point you find a full impression of a foot. From the look of it, the beast must be enormous, in-line with an adult dragon, but much different in its shape. It is humanoid, with four huge appendages that end in what are certainly massive claws. Based on your experience, this creature must surely top 10 feet tall, perhaps reaching closer to 20 feet; additionally its weight must be incredible if the depth of the impression is any guide.
The trail you are following leads into the swampy trees and thick reeds along the river approximately 50 yards ahead.
OOC:
I will be posting an area map later tonight.
