I thought about including as a worldbuilding element something called a Tempest, which is basically a spontaneous supernatural storm that can transport travelers great distances across the world at random. The idea's most immediate use is to explain the presence of human civilizations beyond the known world, but it also offers other narrative possibilities, like transporting characters to entirely new continents, or bringing members of alien civilizations into contact with humans. A very useful tool. But is the idea a bit too obviously DEM or might it be regarded as... this? What do you guys think?
