|Seen In||"The Thing With Feathers"|
A Seltenvogel (pron: ZEL-tən-voh-gəl; plural: Seltenvögel (ZEL-tən-vø-gəl); Germ. selten "rare" + Vogel "bird") is an extremely rare, bird-like Wesen. They have a multi-colored head and beak and glittering golden eyes. Seltenvogels are so rare in the Wesen community that they're thought to be extinct in most circles. Still, this does not mean they are completely forgotten. One appeared in "The Thing With Feathers". They are not very strong, given their long history of captivity, and easy prey for stronger Wesen.
They are prized for developing a brittle, egg-shaped stone made of gold, called an Unbezahlbar, and were enslaved or imprisoned in earlier times and force-fed to produce them. The stone develops in a sac in the Seltenvogel's throat, and if it is not removed, the Seltenvogel can suffocate and die. It can be safely removed by making an incision near the windpipe, taking care to avoid the major blood-vessels of the throat, and then lifting the sac containing the Unbezahlbar out.
The Seltenvogel is based on early myths of a goose that laid golden eggs, which can be found in the original Aesop's Fables, and similar myths from ancient Greece and farther back in Eastern Europe.
