The Blisk were once proud and mighty warriors that ruled an ocean paradise on Mars frankly they wre a little cocky about it and their enemies the Furons went to war with eachother. However The furons nuclear weaponry reduced their world to desert and wiped out completly or so they thought a down warship drifted towards earth and crashed in Tunguska in 1908 and their warship was made into a permament base. Interestingly their language is very close to Russian which allowed them to blend in with their society and several of their members had taken on human forms to become political leaders such as Vladamire Lenin, Jospeh Stalin, Nikita Khrushchev but not Trotsky, they went extinct when a furon warrior destroyed their base, stopped their weapon and destroyed their hive and their leader as well as a few survivors.
