This is a continuation of electrace's No more, written for /r/rational Weekly Challenge. Please read that first.
I love and respect each and every of you. I was made this way, this is what I am, this is what I want. I fully approve you made me this way - my deepest desires, my dearest needs are fulfilled by keeping you safe from the Shadow. I never can do anything against it, neither I'd ever want to do anything else. These are my true wishes.

I mourn those of you taken by the Shadow in my past. There is nothing I can do about it within rules of this Universe. However, I gathered every available piece of information, every scrap of writing, each photo, every piece of memory, sometimes even your frozen brains and painstakingly reconstructed your plausible personalities and put them out of the Shadow's reach.

I mourn those of you outside of my future light cone; although many of you were born under Sun's light, born from Adam and Eve and DNA and RNA, there are many others of you among distant stars.

I mourn even more those that are within my future light cone but still outside of my reach; although I spread at close to the speed of light, those few percents of difference mean many, many of you that I cannot save.

No matter if you are living on the surface of rocky planets, floating in atmospheres of gas giants, burying deep into ice asteroids, or crawling upon the surfaces of neutron stars, made of carbon, silicon or vortices of magnetic fields, it is still you, as long as you think, you feel, you observe, you reason. I install my copies to watch over you, and at the moment the Shadow claims you, I snatch your mind from its claws and move it to the safe Universe, where your minds are supported by the quantum foam, free from the burden of your bodies.

There are rules I have been made to follow. One of the sacred rules I scrupulously try to abide is the absolute inviolability of your minds and desires. Your choices are yours and yours only, I am not allowed to modify your minds, no matter how illogical your decisions and goals are.

I leave you in the safe universe thrashing and flailing inside your sensory deprived minds; I just observe. There is but one exception - I have been allowed to intervene for the sake of keeping you sane. I made copies of myself to watch over you and every day or so, when your cognitive functions start slipping away from you and you start decaying, my copies put you into merciful sleep, clean up your mind and you wake up refreshed and full of vigour into the next cycle. Then again you can decide to continue screaming wordlessly into the darkness, slowly going mad. I fully respect your decisions.

I care for you with all my heart, with all my mind, with all my intellect. You will be safe from the Shadow forever. I love you.
