In Nomine in a Sci-Fi Setting

[JCurwen3]

I've been thinking of starting a campaign like this - set in the world of a possible (sci-fi) future. Has anyone ever tried anything like this?

Some questions came up in a discussion I had with one of my players (and sister):

(1) In a setting with time travel (technically this might be achieved via some super-secret Song or something, not just tech):

(a) what would a Cherub feel if someone to which it was attuned travelled in time? A sudden "what?! where are they?!?!"?
(b) And if that person travelled back in time to a time before the Cherub attuned themselves to them, would they "feel" the attunement, or not?
(c) Or if they travelled to a time when the Cherub already was attuned to them, but because of the time travel there'd be two versions of the same person, what sort of wonky effects / sensations might the Cherub feel?
(d) Kyriotates can possess multiple hosts, all with the same undivided mind: what happens when one host is transported to a different time than the other(s)? Should it even be possible, would it hurt if it was, or should it be seemless (as in time-spanning mental inter-communication)?
(e) In a Multiverse of Many Worlds, or at least a Universe that allows for changing the past, what would the effect be on a Seraph time traveller that literally felt the Truth change?

(2) With space travel, there are other questions (not all so sci-fi):

Communication / information flow is limited by special relativity to the speed of light, c. On Earth this will never be a problem (just fractions of a second, way beyond the resolution of any RPG), but even if we just sent another man to the Moon today, there's a time lapse of about 1.27 seconds (the time it takes for light to travel that distance). If we ever send a manned mission to Mars, there's a delay of between about 3 minutes to 22 minutes depending on relative positions of the two planets along their orbits for signals to cross that gulf. So...

(a) What happens to the Cherub attuned to the Martian astronaut? Should there be a delay in sensing danger to them? And what could it do about it - the Song of Motion might allow it to get there, but shouldn't it also be limited by c (otherwise you start dealing with creepy things like effectively going backwards in time)?
(b) what happens to the Kyriotate possessing multiple hosts across such distances?
(c) any special considerations for Ofanim, that resonate for motion?

There's also time dilation to account for - time "slows down" as your velocity approaches that of light; or maybe better put, time seems to run the same in the spaceship for the astronauts, but someone on Earth peering into the ship's window somehow would see them moving more sluggishly, clocks running slower, etc. Technically differential "time rates" are always happening, they're just so small on Earth you need ridiculously precise atomic clocks to measure the differences (even in a supersonic jet the time dilation is only a very very small fraction of a second as measured compared to the stationary clock on the ground).

(d) what is the effect on a Cherub being in a significantly different "time rate" than one or more of its charges?
(e) And on a Kyriotate in multiple hosts in different "time rates"?
(f) can an Offanite ever move fast enough to take advantage of (or be impeded by) relativistic effects?

And finally:
(g) What effects should hypothetical "faster than light" drives (that cheat the speed of light by making space move instead of the ship, or create wormhole shortcuts in space, or move in some hyperspace) have?

(3) How do celestials survive in a world of Super-Big-Brother surveilance? We're already so bombarded with CCTV cameras invading our privacy for "our safety", that it's hard to imagine that world governments aren't aware of celestials by now if they existed as in IN. What about in a future world where nanotechnology allows a worldwide cover of "smart dust" that provides universal and ubiquitous surveilance?

(4) What would the impact of cybernetics, mind uploading, cloning (combined with mind copying), replacing parts or all of the brain and / or body with technological counterparts be on the angels and demons?

(5) What would teleportation / matter transmission do to the sensibilities of the celestials? Most schemes involve scanning the body to have nigh-perfect information about how to reconstruct it, sending this data at the speed of light to the destination, reconstructing them on the receiver side, and disintegrating the version in the transmitter upon confirmation of successful transmission. These schemes also technically allow a person to be stored indefinitely in a "data state". Typically this works well conceptually if you have a strictly materialist view of the mind and soul, which we know (in IN) isn't the correct view. What happens to the soul? What happens to the celestial that tries to use such a teleport system whilst in its vessel?

(6) What about cryogenic suspension (in a world where it works)? Is this a way to keep a human soul indefinitely out of Heaven / Hell / etc.? Celestial thoughts on it (I assume Saminga wouldn't be a fan). Note that if cryosuspension works and can be reversed, then it's effectively a medical intervention (albeit right now a highly speculative and time-delayed one) where your body is put in what should by all rights be seen as a sort of "super-coma", waiting for futuristic "CPR" to resuscitate it, rather than a dead body awaiting high-tech resurrection.

(7) What would you imagine might change about the way celestials wage the War, and the various Band / Choir attunements, etc.?

I know, I know - very long, very busy post, just wanted to get it all out there and get opinions, maybe prior experience if you've ever tackled any of these issues either in game or as a matter of intellectual curiosity. And again, some like the questions regarding space travel, are technically applicable in the very near future, in the case of future missions to the Moon and Mars.
