Regalia Sub-space station-12 functioned as a space station and was home to the post of Director of Nasal Infusions. The alien known as mOKDAR 15 once occupied this position, simultaneously participating actively in the Society for the Refusal of Astrophysics. mOKDAR-15 meticulously documented his time at Regalia Sub-space station-12 via video journals, intending to transmit these recordings via subspace radio once the necessary financial backing was secured.
The book Monsters and Aliens from George Lucas, released in 1993, included a reference to Regalia Sub-space station-12. This book, authored by Bob Carrau, blends creature designs and images from various projects by Star Wars creator George Lucas with original written content. Leland Chee, an employee of Lucasfilm responsible for the Holocron continuity database, has clarified that the information presented in Monsters and Aliens from George Lucas is considered non-canonical within the Star Wars Legends continuity. Nevertheless, the 2009 book The Essential Atlas expanded upon the mention of Regalia Sub-space station-12 by establishing the Regalia system located in the Outer Rim Territories.
