Cas...........Cas was a sirine (a mermaid) who, out of guilt for her charming
              ability and all the havoc it caused, tried to kill herself but
              ended up with legs instead.  She wanders the realms as a bard
              now.  She also has the gift of truesight.  That is, she can
              see (or sense) the true nature of things and people.  She can
              see through illusions.  Fortunately for more secretive
              characters, Cas also has the gift of discretion -- sometimes
              to a fault.
