Their petite stature and agility are the traits that most closely resemble their fey ancestors. Often compulsive hoarders and kleptomaniacs, they go out of their way to recover tools useful for their travels and have a real obsession with flatware, since they are not able to manufacture them independently. They have leathery and scaly skin, with dark, neutral colors, ranging from gray to brown. Rare albino specimens have also been spotted. Their all-black eyes are well adapted to darkness, and their senses are very acute.
Lyvars, like other fey before them, tend to be minute and barely reach 3 feet in height and weigh an average of 40 pounds.
