The Severance
In the year 2290 - sixty years after the second colony ship arrived at the Celassi star system and entered orbit around Raana, the Celassi quantum gate mysteriously shut down, making the return trip to Alpha Centauri and Earth impossible. This happened almost 200 years ago, and marked the beginning of a period called The Great Chaos.
The Historical Society continues the debate why The Severance happened. It remains the biggest mystery of all. A troublesome sound recording logged just prior to the malfunction hints that something attacked the quantum gate at Alpha Centauri.The crucial question is by who? Or by what?
No other intelligent alien civilizations are known to humanity - other than the mysterious builders of the quantum gates that link dozen of star systems together - and there were no brooding conflicts between the central star systems when the severance occurred.
