This story starts with my version of "Starcraft 2: Odyssey".

The Kardyan Quadrant was once a battlefield, in a galaxy wide war between two species: the Protoss and the Zerg. The Protoss sought to expand and colonize. While the Zerg wanted to consume everything in their path. They fought for centuries, until both wiped each other out.

Millions of years later, Terrans (humans) colonized the planet Parsya, after being exiled from earth, to prevent overpopulation, the event was known as the "Great Exodus". They found a new home among the stars.

The "Powering Wars" story is the same as the one in the custom campaign, up to the events of Duros III.

For ten years the "Federation of Warfare" stood as the supreme power in the Kardyan Quadrant, their only competition was the Exodus Clan but they didn't bother each other, until the Rebellion on Duros III, where the miners revolted against the harsh conditions they were forced to cope with, it was a situation that the planets defense squadron- the Hell's Rejects- weren't prepared for. The Soulless Ravens were sent in- accompanied by the battlecruisers Heindall and Pegasus.

After thwarting the Rebellion, Major Jared Harsh (promoted after the Revolt) had to fight not only the Federation- who framed him and his men for the murder of a group of scientists- but the UEC (United Earth Coalition)- which was formed as part of an Act to conquer the Kardyan Quadrant- and a race of insect-like aliens, brought back by Federation scientists.

With the help of Doe- a former intel agent- and the Rebels, they and a few thousand refugees escaped into the unknown regions of space. But not before stealing something from the Hydra Complex -a research base where two different alien remains were being studied.

The UEC then nuked the planet in order to destroy the aliens and began their invasion of the Kardyan Quadrant.

The aliens on the surface of Duros III were killed, but not the ones below.
