This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Cherufe (Mapuche)
The Cherufe is an evil humanoid creature made of rock crystals and magma. It is said that Cherufe inhabit the magma pools found deep within Chilean volcanoes and are the source of earthquakes and volcanic eruptions. Cherufe are also said to be the source of "magicians' ardent stones" (meteorites and volcanic stones) that cause damage in volcanic regions.
The only way to abate the Cherufe's appetite for destruction was to satiate the beast's taste for human flesh by throwing a sacrificial victim into the bowels of its volcanic home. Much like the European dragon, the Cherufe's preferred delicacy came in the form of virginal maidens. The mythological origins of this beast may have originated to explain anomalies of geological events such as volcanic eruptions.
