Mistspren

Mistspren are a subset of spren that exist on Roshar. They are capable of forming a Nahel Bond, granting people the abilities of the Order of Truthwatchers. They are closer to Cultivation than to Honor.


Mistspren resemble the shimmer light makes on a surface when it is reflected through a crystal in the Physical Realm. When they stay still, light grows upwards from them in the shape of plants, which retreat when they start moving. 


In the Cognitive Realm, mistspren have bodies made out of fog, and a porcelain mask on their face. Their clothes are not part of their essence, but interact with their body as though it was solid. Their masks twinkle when they catch the light, and almost appear to be made of translucent crystal. The mask's expression does not change, and the lips do not move when the mistspren speaks. Though they generally are humanoid, mistspren are capable of taking on other forms, unlike most sapient spren. 

Mistspren voices seem to have a tinkling or chiming quality.
