"Create your own world,
Invent technologies or magic to change the Laws of Physics, and/or the rules of society,
Populate it as you wish, no gender or species for your characters is specified."
Maybe we should have been more specific ... Nah!
We got fairies, met in woodland groves; ones that explain the true nature of the world, some taking you home to meet their family while others whisk you off to Venus.
Meanwhile, in other dimensions or times people adventure through temporal holes, across the depth of space to encounter aliens, some brilliant others stupid enough to be politicians. Meet Scientist who can change the nature of planets and hunters of people and the Zarak.
