Alphabet, Gorean (noun); composed of (probably) 28 characters derived from the various alphabets of Earth, such as Greek, Roman, oriental or Cretan influences, among others.

Note: read but the description of the Category Alphabet, John Norman claryfied some.

The Gorean alphabet has twenty-eight characters, all of which, I suspect, owe their origin to one or another of the alphabets of Earth.
