The Sullen

The Sullen, are a dark shadow creature that has the ability to shapeshift and feeds on sentient race's souls. Little to nothing is known about them, though is guessed that they are constructs of natural dark magic, that have leaked into this universe. Their motivation is unknown, it is believed that they just live to feed.

Biology and Behaviour
Absolutely nothing is known about their biology if they have any. All that is known is that they must feed on sentient souls to survive. They do this by luring people into lonely places and stalking them. If a person notices that they have more than one shadow per light source it is often too late for them. As a person becomes more scared, their defences fall and the Sullen will embrace them and suck out their soul. The victim is left wandering mindlessly alone in the dark until their body runs out of energy and collapses. Sullen are found mainly in forests, particularly evil ones, and they spread outwards from here. Sullen have one weakness. Because of their shadowy nature, they fear and can be damaged by direct light of any sort.

Relationship with Sentients
Almost all Sentients fear the Sullen, but likely none more than the humans of Kotlas. In the snowfields of Northern Torun, Sullen are particularly common due to the Nearby evil forest and the long dark winter nights. This is the primary driver that lead to the Kotlai discovering fire magic. Cities in the Grand Duchy remain brightly lit throughout the night to ward off the terrifying cretures. Despite all these measures, more Kotlai are taken by the Sullen than any other race.

The Knorrig of the dark forests on the other hand, have developed light magic in order to kill dark creatures. This has proved reasonably effective in protecting their larger settlements.
