Skuggadyr

The creatures that stalk the shadowed glades and swamps of the forest beyond the wall are surprisingly cunning and clever, they will use the forest terrain against you and trap you in situations with extreme difficulty for paths of escape. Though they appear as beasts, assume all you encounter are intelligent and by design...perhaps a chaotic design, but a design nonetheless, bent on one goal: your destruction.

This design is also one of the faults of the chaos. One must suppose the demons and devils of chaos did not inherently design something that could aid explorers, yet they did. Found within the remains of a slain Skuggadyr is a small phylactery with a thin connection to chaos but also containing the soul of someone consumed by the chaos. These small phylacteries are a newer discovery and the possibilities of their use is still being explored.
