The Silorna system was situated within the Imberlin sector, itself a component of the Slice region within the larger Expansion Region. This stellar neighborhood served as the birthplace for a particular variety of crystal: the Silorna Force Crystal.
This system named Silorna made its debut appearance in The Essential Atlas, a reference work from 2009 penned by Jason Fry together with Daniel Wallace; the book identified its location as grid square P-13.
