Quail-en-kalumen

The Quail-en-kalumen were an extinct spacefaring species that existed during the 1st Florescence around 4.6 billion years ago.

Culture
An example of Quail-en-kalumen culture was the soul flute, a very rare artifact. Rumor had it that the soul flute created the most extraordinary sounds any living being could hear, so wonderful one's soul would leap at hearing them. Any sapient blowing the flute would become its soul slave forever, eternally trapped even after death in the mysterious metal of its forging.
