Lorina, also known as Daran IV and New Fabrina, is a class M planet located in sector 54R, somewhere in the space of the galaxy's Alpha or Beta Quadrant. The fourth planet in orbit of the Daran star system, this world was settled in the year 2270 by the Fabrini as their civilization's new homeworld, after the arrival of their worldship 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.
