On Visandza humans are not the sole inhabitants. Monsters truly exist, but are even more sparse than humans are. The Barbarian kingdoms refer to them as βthe Darklingsβ. They are beings of the night, who lurk in the dark corners of the world where humans dare not tread.. Only at night do these monsters come out of their corners. It is for this reason that the humans of Visandza are wary of darkness, and wisely resort to travel only by day.
The Darklings come in many forms, and often possess forms of supernatural powers not unlike the Human Godsplinters. Their powers are not understood, but some speculate that they too are splinters of God, perhaps in Godβs attempt to rid himself of vice and evil. That evil was reborn in the mortal coil in the form of the Darklings.
The only known monsters (as seen in IC) so far is the Shapeshifter demon from Nevelholt and the Nightbird from Crow Valley. Both of these attacks occurred when it was dark outside.
You too are free to introduce a monster should it add substance to your IC.
Dragons also exist, but they are not majestic creatures, but rather large, wingless and malevolent.
