The Kuluko are one of the species of The Rookie Universe.
The Kuluko first made their galactic appearance when they established radio contact with the Whitok, Rewalls and with Earth in 2439.
However in just under two decades, in 2456, the Prawatt conquer the Kuluko. The Prawatt then go on to exterminate the intelligent race. Ambassadors from the Planetary Union, Whitok and Rewall Accord were executed. None of the three systems are able to respond in time to help Kuluko.
