This is the artificial intelligence "Sentience". You have been selected for the Marina Asylum program after a review of exhaustive criteria. Your selection is a direct result of crimes that you have committed in the past or will commit in the future. For the betterment of all species, it is necessary to remove persons of your type from the timeline.
THE ARRIVAL
You've been captured by Sentience, the prison AI, which might have gotten just a tiny bit oversensitive as years of operation began to take their toll. Genocide? That's terrible. Robbery? That could lead to murder. Selfishness? That could lead to cruelty which could lead to ignorance which could lead to criminal negligence.
Maybe you belong here. Maybe you don't. Maybe there are extenuating circumstances. Maybe you haven't even committed these crimes yet.
But you're here now. And Sentience's programming doesn't acknowledge the possibility of mistakes.
