Hetnagaro, a planet ravaged by the Galactic Empire during its imperial era, had suffered this fate by 4 ABY. The New Republic pilot Kairos, flying a U-wing, sought to avenge the destruction of Hetnagaro, along with other planets such as Alderaan and [Nacronis], by dismantling the Empire.
Alexander Freed's novel, Alphabet Squadron, released in 2019, included a reference to Hetnagaro.
