It isn’t as advanced as JRR Tolkien’s languages or Klingon for that matter but it is interesting the Stargate fans has compiled a lot of information about the Gua’uld language spoken by the Gua’uld and the Jaffa.
I guess one of the reasons why I like Stargate SG-1 is that it is a lot about the danger that arises when a large number of people left their destiny in the hands of false gods who use advanced technology to perform ”miracles”. It begins with the enslavement of ancient Egypt by the Gua’uld and later with the preechers of the Ori who kills everybody who do not believe. Of course the rest of the component in the show about the possibility of contact with life on other planets and how to react to different ways of living the life. Of course all of that is present here on earth but the added mixture of different life forms, advanced technology and huge distances makes it even more exciting.
