|Race||Half Elf, half Vala|
Vairë tells to Eriol about Tinfang Warble, a spirit who is half fay of Palúrien and half Elf (Gnome or Solosimpi). He was a flautist whose fluting had an enchantment, and the stars twinkled according to his notes. Not even the Solosimpi could rival his fluting.

enchants on summer nights of June
and kindles the pale firstling star..."

The meaning of Tinfang is "star-beard" (from tinu "spark, little star" + fang "beard"; found in The Etymologies of The Lost Road).[source?] He apparently was one of those few elves who grew beards during the first age of their life, like Mahtan.[source?]
Gelion can also be found in several other compounds.
His name probably comes from an earlier poem Tolkien penned named Tinfang Warble, about a fairy-bird.[source?]
