Some ideas for a sanctuary campaign:
* Mutiny: the crew is divided on a very difficult moral question, in example if to hide or find survivors and if leaving the survivors as bait gains them a run for the jumpnode. Loyalty clashes with desperation.
* Betrayal: the facilities on the ship were damaged during the escape. There are too many mouths to feed, too many lungs that need to breathe. Part of the sleepers must not wake up, but it has to look like an accident.
* Truths: Some of the sleepers experience Nagiri and find out what the Shivans and Vishnans want. They try to reach out to Hammer of Light dreamers but the fanatics instead become an enemy, desperate to enforce the great destroyer's plan.
* Hope: Part of the crew colonizes a world of the ancients, finding out about the connection between subspace and realities. They trigger the wrath of something horrible which instigates the culling of our main universe in fear of change to which it can't addapt. A certain and former GTI officer named Aken Bosch informs his main universe counterpart where to find and how to finish the work he started. Evidence he finds in the ancient ruins show that the Vishnans must not be trusted, his counterpart can only turn towards the enemy.
* Lies: Very dark choices are made to preserve the sanctuary and the knowledge of the Nagiri gifted within. The ship is a key to close or open realities and for it to exist means that Earth had to fall for a sinister but nescessary reason. But to escape from this reality it needs allies from another reality to see it safely out into our realm. It sets the plan in motion to draw the unsuspecting Orestus and her fleet to their version of Sol, delivering Bei to the Vishans, in return for survival and protection for all of mankind from the Shivans. But promises are broken and as a result judgement will be passed.
