Itropa is a mod for Neverwinter Nights. It is a mix of sci-fi and fantasy. It takes place in an alternate universe, where technology has developed at a different rate than our own. For example, they have teleportation, but never invented cars... but why would they need cars, when they can teleport? Admittedly, most of Itropa's choices of scientific development are actually rationalizations for limitations of the game engine. The true goal was to create a sci-fi-esque universe that doesn't require any additional hakpak downloads, other than the CEP.
