Winchester: Saviour

The year is 2795. The Human race has evolved and expanded, colonising many new worlds and learning to share the galaxy with thousands more new lifeforms and civilisations. Many of these races have banded together to form The Galactic Confederacy of Planets, where the immense diversity of cultures and enlightenment has enabled our united species to reach levels of universal knowledge, exploration and understanding, only ever dreamed about by generations past.
However, all of this has come at extraordinary costs. Our history has been marred by horror and oppression. Earth has had to rebuild almost the entire civilisation from scratch. Three hundred and fifty-two years ago, the galaxy's balance of peace had been overturned when a brutal, savage race of beings invaded our region of space. Calling themselves the Dimion Imperium, these merciless barbarians ruthlessly slaughtered any one who opposed them, including millions of humans. They destroyed entire worlds and conquered many races, our own being one. Over the twenty years of their oppressive domination over much of Galactic Confederate space, secret under-world rebellion groups slowly built up defences against the Dimion. Eventually, but not without severe Confederate losses, they were defeated and banished to the deep, uncharted frontiers of space and time, never to be heard of again.

But something has gone wrong in this new age of peace. A Confederate ship has gone missing 14,000 Light years from home. The CGV Winchester, Admiral Franklin's personal project for the last five years, is commissioned early to investigate, however things are far worse than the crew could ever imagine.
