Music like Crystal Bats

The characters from the 1982 cult fantasy film The Dark Crystal series were created by puppeteer Jim Henson and concept artist Brian Froud, most of the information about specific characters and species names that were not mentioned in the film come from supplementary materials such as Froud's book The World of the Dark Crystal. The series expanded into books, comics, artwork, games, and the 2019 prequel series The Dark Crystal: Age of Resistance.

Gelflings are slender, elvish humanoids with protracted facial structures who originally populated most of Thra, having three long fingers and a thumb on each hand. Female Gelflings have butterfly-like wings that can be folded to fit easily under their clothing, allowing them to safely glide down from high places, even with the added weight of a second Gelfling holding onto them. The Marvel Comics adaptation of the film states that in the past, females could fly, but the wings have become vestigial. Gelflings also possess an ability called "dreamfasting" that allows them to psychically share thoughts, memories, and emotions through touch. The name "Gelfling" is a transliteration of Ghel-lflainnk, which means "those who live without knowledge of the future". This is due to their innocence and naïvety.
