In Fiction

In the computer game Frontier: Elite 2, one of the planets you could choose to start the game from was an ice world similar to Europa in orbit around Ross 154. This planet was named Merlin and its primary export was fish, harvested from the liquid ocean that existed below the icy crust. Frontier: Elite 2 is a computer game written by David Braben and published by Gametek. ... It has been suggested that Europe (disambiguation) be merged into this article or section. ...
