"Real life" names are allowed; but they must not belong to a celebrity. People playing PlaneShift shall not meet a character with a name that makes then possibly biased of expecting a specific look, character, behaviour...
Wikipedia knows "Paul Henderson" as journalist (winning a Pulitzer Prize), cricketer, footballer, lead singer, sailor (in a Hall of Fame), Australian politician ... I believe that name, specifically, is quite famous, that won't be accepted.
