The "skuthro" are a race of floating faces formed out of raw emotions. Each is named according to the characteristic expression of the emotion it embodies (e.g., scowler, screamer, smiler, sulker, etc.). They are numerous and often dangerous, considered by some to be a form of wildlife within the Astral.
The more developed they become, the less susceptible to influence they become, even to the point of Reflecting it back.
