A gloom demon is a vaguely humanoid shadowy form, but its appearance is unstable, coiling and twisting, from moment to moment changing in size anywhere from five to seven feet. Even its position is erratic, seeming to change by one foot or more in a random direction every time an observer blinks or looks away. Gloom demons are native to a particularly dismal part of the lower planes where deep shadow and darkness prevails, and nothing has permanent substance.
