Uvodni-Malakh War

A war opposed the Uvodni Empire and Planetary Alliance to the Malakh Empire, officially ending with the signing of a peace treaty. Although the Uvodni were native to the Dragon Nebula, Sarah Jane Smith recognised this war as being part of "the Ghost Wars of the Horsehead Nebula".

Origins
The Malakh Empire were known for their aggressiveness. Sarah Jane Smith once said that they would start a war against you "just for looking at them".

The war began several centuries before the 20th century. (TV: Warriors of Kudlak)

Later battles
The Uvodni Empire was backed by an alliance of other races. However, the Malakh eventually defeated them all. Because of this, the Uvodni needed to find some more allies, and fast.

They came upon Earth and found that the native sapient species, the humans, were a good choice as they were naturally aggressive. In the 20th and early 21st century, the Earth missions were controlled by General Uvlavad Kudlak, who was taken from the front lines due to injury, and his Mistress, a computer. Their aim was to abduct human children to send off to the battlefields. The mission was carried out under the futuristic war game Combat 3000. (TV: Warriors of Kudlak)

End of the wars
The wars ended with a truce between the Uvodni and the Malakh and the Uvodni Emperor ordered the Imperial Fleet to return home, but the Mistress was not designed to recognise peace. She hid the message from General Kudlak for ten years until found by Luke Smith after hacking into the computer systems of Kudlak's warship in the 2000s. Until then, Kudlak continued sending children onto battlefields.

Kudlak was shown the message. Angry at the new-found knowledge that his Mistress was a computer and that ten years and many innocent lives had been wasted, he destroyed the Mistress. He sent the children on board his ship back down to Earth, where they were returned to their families. He returned to his homeworld to find any surviving children from previous transmissions to the battlefields to return them back to Earth. (TV: Warriors of Kudlak)
