The Vanjervalis system existed within the Colonies' Slice region. Its designation mirrored that of both the Vanjervalis Systems computer corporation and Rendili/Vanjervalis Drive Yards, a starship producer situated on the Core Worlds planet of Corellia.
The reference book The Essential Atlas, published in 2009 and written by Daniel Wallace together with Jason Fry, initially introduced the Vanjervalis system, locating it at grid coordinate N-11.
