Antipositional Moves

The peoples of the galaxy are no longer alone in their fight.
The invaders – called the Ditufgne – have an enemy with equal or perhaps greater force at their command - The Xorcerizts.
This new - but familiar - race has an offer that not only gives everyone a fighting chance – but could fundamentally change the make-up of governance across the galaxy.
The crews of the Dawnstrider and Ravusqan Raider find themselves unexpectedly in the middle of history. Alvon Gargarm and information broker Avra Pii K'tark'ah have key roles in discussions that might reshape interplanetary policy.
But many questions remain. What is the motivation of the Ditufgne? Are the Xorcerizts truly intent on helping the races under attack? Can the disparate peoples work together to resist the incursion?
Is the end of the incursion near – or is there worse on the horizon?
