Flitterwaifs were waifs which inhabited the Nightwoods. Just like all other waifs, Flitterwaifs were capable of speaking using only telepathy.
Flitterwaifs appeared to be the most arboreal species of waif, and possessed sharp, hooked talons which enabled them to grip onto branches of trees easily. Additionaly, they were carnivores, and were able to ensnare their prey by deceit through feeding them lies. These waifs were also far more savage in manner and appearance than most other waifs, with sharp fangs and being the only known waifs to possess wings, which were leathery, giving flitterwaifs a close resemblence to bats.
