With a century to plan, the Gufwin took the Dravixians completely by surprise and the captured the whole surface portion of the planet in a matter of weeks. It was when they attempted to explore the caves that they began to loose their own. The Dravixians had never been in a "race" war and they had never learned the arts of war, but they went on instinct and their instincts were good. They wiped the invading force out as they entered into the caves. The Gufwinn were simply outmatched in the Dravixians' chosen element. In a few months, the whole Gufwin invasion force was wiped out as well.That started the Decades War. In the end, the Gufwin were completely wiped out and very few of the Dravixians survived. The two races turned to ouright xenocide. Both planets were turned into slags and now these planets are used as literal "waste dumps".
