Fell dragons make their homes in the wilderness of the Fell Zone. Their hides help them to blend into the many leaves blanketing the ground and they tend to attach themselves to the trunks of trees better lie in wait for food.
Fell dragons are much smaller than normal dragons and bizarrely carry the characteristics of both chameleons and spiders. Like chameleons, they can change the colour of their scales to match their surroundings, allowing them to ambush prey from out of the blue. This camouflage seems to always be active, as the first Fell dragon that confronts Rye and Sonia changes the shade of its feet to the leaves it steps on while they were previously brown from tree-bark. They seem to constantly drool a thick saliva from their mouths. This plays into their similarity to spiders- by using the many trees in the Fell Zone, the reptiles are able to build sticky webs that run in between the trunks for prey to blunder into. These webs are strong enough to restrain a human, but can be cut out of.
Fell dragons display high aggression to anything that wanders into their territory. They hide themselves near their webs and reveal themselves when it is time to feed. Fell dragons seem to be solitary creatures, as each has its own web built a small distance from another. Their aggression also extends to each other, as they will fight over food if another dragon tries to take it.
