Blacktrons

The Blacktrons are a mysterious and terrifying race that wage ceaseless war against the Empire and all other dominions of man. Through their mastery of stealth technology they are nearly unstoppable.

Blacktron space extends nearly to New Jerusalem and Regis Major, a fact Spaceman of Futuron makes use of when he journeys to the closest planet in Blacktron space to seek their aid against High Lord Spruesworth. He arrives carrying three huge slabs of blockonium as payment; the Blacktrons know who Spaceman is and that he seeks to dethrone Spruesworth, but mistakenly believe he still possesses the treasure paid to Rom the Space Knight and Azimuth of the Ice Men. In return for the blockonium they provide Spaceman with a shadow field generator.

Jadar of the Oasian miners is one of the only people known to have seen what a Blacktron looks like under the visor.

When Dipolus reveals the shrine of Polaron to SX3 and Yoren of Futuron, he claims that the saint united his clan in the days of the first Blacktron incursion.

Yoren later identifies as Blacktrons the figures in an ancient tapestry he claims dates back to the Second Great Age of Man, "before the days of the Valor Squadron, when the Blacktron did turn from the ways of men and took on their terrifying visage".
