AVILETS
Avilets are a Closed Species created by SauntProof.

Avilets are an ancient spirit species that vanished for years. They were thought to be extinct, leaving no traces behind besides their belongings. However, after many years of silence, Avilets began reappearing in quite large numbers with no memory from the time of their disappearance nor how they disappeared in the first place. This raised many questions as to how a whole civilization could vanish and appear again out of nowhere. The return of Avilets is so recent that much remains unknown of them outside of small tidbits, but research is being done on the species and their history. Perhaps someday more will be known about their history and disappearance...
