|Chronological and political information|
Kassar Kosciusko was a friend of Meysen Kayson, having saved Kayson's life on Pernam Minor. Shortly after the Battle of Yavin, Kosciusko was known as "Mr. K," the owner and operator of a casino that was located on Kwenn Station. Kosciusko had a long scar on his face, the result of an attack by the Loag, a group of assassins, on Novor 23.
Kosciusko kept a cell of Rebel operatives on Kwenn Station, but their activities were often disrupted by Imperial-aligned spy Derrida. After foiling at least five Rebel operations in Kwenn, Derrida became Kosciusko's personal nemesis.
