Definition of the word: Xerkinski
Xerkinski - Xerkinski was once the fourth planet of the Star Registry™ system on the opposite side of the local group. A cordial misunderstanding of an incident some years back stemming from an alleged mix-up between shuttle blast protocol and the desires of a particularly zealous ship commander led to a situation of modest incidental damage. Much of the universe, for reasons unknown, chose to document and publish the incident as if it was newsworthy.
The planet Xerkinski had enjoyed one of the longest continuous civilizations in the Milky Way, but following an ambassadorial visit from Alpha Squad 7, a minor clerical error is hypothesized to have charred the planet beyond habitability and sent it hurtling into its sun. Although the matter was reported as true, the only surviving witnesses were the crew of the ship that caused the infamous oopsy-daisy, and that crew never corroborated the so-called "facts" of their having destroyed the entire planet.
Wars were subsequently waged and many hundreds of planets ultimately faced entire destruction, but no crew members of Alpha Squad 7 were ever proven to be responsible in kangaroo courts of quasi law. Critics suggest the legal proceedings were inherently flawed since all crewmembers were judged by a jury of their peers, who by definition, had all also been accused of destroying a planet by carelessly casting it into a sun.
