Wikipedia: Saran (plastic)
Saran is a trade name currently owned by S.C. Johnson & Son, Inc. for a polyethylene food wrap. The Saran trade name was once owned by Dow Chemical for polyvinylidene chloride (PVDC), along with other monomers. Since its accidental discovery in 1933, polyvinylidene chloride has been used for a number of commercial and industrial products.

My elves tend to be “Cosherdil,” or perhaps “Rei Saroni.”  I once had a human thief named “Manuel Dexterity.”  And I loved my paladin, “Sir Anrapp.”

I always used bizarre names for characters.  My first was a Dwarven fighter named Anvilhead.  After that, it got more creative.  Cosherdil Half-elven was one of my favorites, as was an elven mage named Rai Saroni. Another favorite was my paladin, Sir Anrapp.
