The Fromiria system existed within the Mortex sector, which itself was situated in the Trans-Hydian region of the Outer Rim Territories. Notably, it was the place where the Fromirian roast queg food originated.
The system of Fromiria initially appeared in The Essential Atlas, a reference book from 2009 written by Daniel Wallace together with Jason Fry. This book identified its location as grid square R-5.
