A very whispery name, not so much alien as it's reptilic, but I felt like the contest needed a few more original names instead of "The [blank]" or "[Greek word] from Greek". 

The pronounciation is meant to be "sheh-ah-sah-th". The original idea was "Shayssath", but I figured you English speakers would read it as "shae" instead of "shai" anyway, so I made it easier.
