The elder things are an ancient race from outer space that travelled to this world millions of years ago. Their once mighty civilisation has collapsed and the elder things have moved underground or to the bottom of the ocean. Elder things are twice as tall as a human, have conical bodies, tentacles and leathery wings. They are very intelligent and communicate via telepathy in both directions. It is said that elder ones can switch their bodies or even move into the bodies of a member of a different species. Elder things have wings, but do not seem to be flyers.
