"One of history's tall tales? Maybe. But a generator capable of existing in hyperspace and realspace simultaneously would be bad news. Fortunately, nothing suggests the Empire has made any breakthroughs."
―Haxen Delto, in a report to Airen Cracken[src]

The Mass Shadow Generator was a rumored superweapon in development by the Galactic Empire that could simultaneously exist in realspace and hyperspace. The generator was part of a report by Haxen Delto on Imperial weapons projects and incorporated into The Rebel Files.


The Mass Shadow Generator was a superweapon that could allegedly exist simultaneously in realspace and hyperspace. Although a Rebel Alliance report conceded that the generator may be nothing more than a tall tale, it was depicted within the same report as being axially symmetrical in design. In the center, a pair of square pyramids—with truncated tops—was joined by their bases, with a trench running along the connecting line. A smaller truncated pyramid was mounted on top of each of the central pyramids, with two dishes in turn being located atop the smaller pyramids.[1]


Sometime between the years[1] 5 BBY and 0 BBY,[2] the head of the communications unit of Alliance Intelligence, Colonel Haxen Delto, submitted a report to Chief of Rebel Intelligence General Airen Cracken on the matter of Imperial superweapon projects. In the report was a segment that regarded the rumored Mass Shadow Generator, and although the prospect of the generator worried Delto, it seemed to him that the Empire had not made any breakthroughs in development. Delto also mentioned the possibility that the Mass Shadow Generator was one of history's tall tales.[1]

Delto's report was eventually incorporated in The Rebel Files, a central data repository containing a non-electronic copy of sensitive information. In 34 ABY,[3] The Rebel Files were uncovered in the ruins of the Tak-Beam complex, a Rebel Alliance base on the Mid Rim world of Durkteel.[1]

Behind the scenesEdit

The Mass Shadow Generator first appeared in the new canon in the boxed set and reference book Star Wars: The Rebel Files, which was released on November 21, 2017 and authored by Daniel Wallace.[1] It had previously been featured in the Star Wars Legends video game Star Wars: Knights of the Old Republic II: The Sith Lords, released in 2004.[4] The physical appearance of the canon Mass Shadow Generator closely resembles that of the Galactic Empire's Gravity Well Station, which appeared in the 2006 Legends video game Star Wars: Empire at War.[5]


Notes and referencesEdit

  2. Star Wars: The Rebel Files establishes that 14 AFE and 19 AFE in the Imperial calendar are respectively 14 and 19 years after the Proclamation of the New Order. Because Star Wars: Galactic Atlas places the Proclamation in 19 BBY, it can be deduced that 14 AFE corresponds to 5 BBY and 19 AFE corresponds to 0 BBY.
  3. Star Wars: The Rebel Files establishes that The Rebel Files were buried on the same day as the Battle of Endor, which takes place in 4 ABY according to Star Wars: Galactic Atlas. Since Star Wars: The Rebel Files also establishes that the files were rediscovered 30 years later, it can be deduced they were uncovered in 34 ABY.
