Wisp Fiend

Appearance: These creatures resemble the ethereal, glowing lights of traditional will-o’-the-wisps, but they are far more malevolent. Their light flickers between soft, inviting hues and sharp, sinister shades of red and violet. When looked at closely, their cores reveal tiny, distorted faces twisted in agony or mockery.

Behavior: Wisp Fiends are tricksters that enjoy leading people astray, but unlike their fey-like counterparts, their goal is to cause harm. They lead travelers deeper into the dark parts of the forest, where other creatures await, or into natural traps like bogs or ravines. Once the victim is lost or injured, the Wisp Fiends drain their remaining energy, growing brighter as their victims grow weaker.

Purpose: Created as both sentries and traps by Isolde, these fiends patrol the borders of her domain, protecting her territory by leading potential threats away or to their doom. However, their erratic nature means they sometimes act unpredictably, even drawing in creatures that Isolde did not intend.
