Lorina, also known as Daran IV, is a class M planet in sector 54R's Daran star system, which was settled in 2270 by the Fabrini after the arrival of the world-ship Yonada.

As of 2273, the planet had a city in which a large number of the Fabrini lived, along with a number of farms outside the city. A number of underground passages were also created for the Fabrini to live in - after centuries of living in such passages many Fabrini felt more comfortable living in those rather than above ground.
