The Umbra is an accumulation of items that resulted in something useful. The origins of the machine lie in the Spectral Series development program for the unmanned fighter of the Word of Blake. The priorities changed, however, so the technicians created a fighter for reservist use. The Coalition forces of Devlin Stone had conquered Terra before the project was finished.[1]

Stone's engineers searched former production sites for useful technologies and discovered that the Word had built several Umbras. The fighters were close to operational but the work was not finished. The available information gave the technicians an idea of the capabilities of the design.[1]

The armed forces of the newly formed Republic of the Sphere recognized the strengths of the design. The Republic Armed Forces had lucked out because the Word of Blake had not enough time to destroy their research successfully. After a few short years, production of the design started on Terra.[1]

Weapons and Equipment[edit]

Initially, the design was created to be a clone of the successful Shade OmniFighter. Circumstances forced the Blakists to build the Umbra as a dog-fighter. The Word of Blake chose the combination of the Snub-Nose PPC with wing-mounted ER Medium Lasers to accomplish that goal. The 240 XL engine provides the machine with enough thrust for fighter interception and for ground support.[1]
