Magical Settings at this TL

  • Classic: Old West: Generally a very magic poor High Fantasy setting. What magic does exist is in the possession of Native Americans and alchemists.
  • Classic: Steampunk: This where the line between the supernatural and science starts blurring. Magic as a force is dismissed out of hand but supernatural forces are explained via science. For example, Henry Moore's 17th century concept that ghosts are in reality 4 physical dimensional beings is promoted by Johann Karl Friedrich Zöllne very late in this TL[note 2]

This list is taken from the GURPS Repository.
