Saturnalia

The Virtus Fides was a proud craft of the Imperium, a millennias-old empire. Upon completion of its thirteen-month mission above the primitive world of Arago, the crew takes part in the Mid-Winter celebration before embarking on their next mission. Strange blue lightning soon disables the station. 

Tarquin and Arrius, officers of the Imperium, come face to face with the source of the mysterious blue event and discover the true meaning of "brotherhood and loyalty".
