The Febrini system, a part of the Inner Rim's Slice region, resided within the Hapes Cluster's Gateworlds. This system was connected to the Sargon system of the Gateworlds and the Rynmar system in the Hapan Rim Worlds via the Rynmar Trail hyperlane. Additionally, another hyperspace route provided a link to the Zadaria system within the Gateworlds. The creatures known as Febrini sand-prestors inhabited the Febrini system.
Daniel Wallace and Jason Fry introduced the Febrini system in The Essential Atlas, a reference book from 2009. This book placed it within grid square O-9.
