I didn’t lie to Exetera! I said the box exploded – I didn’t say the explosion killed the guys.
So, an addendum to my statement on the “truth” of the World of Darkness: Mages are correct about how the world works, but there is a level of spiritual reality above (or below, or beyond, however you want to conceptualise it) the world that works somewhat differently. This world is largely the domain of werewolves and other skinchangers, but mages can explore it as well (and, in fact, one whole Sphere of Magick is dedicated to doing so). Vampires have virtually no interaction with the spirit world, though as I have previously mentioned some Kuei-jin can travel through it.
The Technocracy views everything through the lens of science, and their understanding of the spirit world is no different. While traditional Mages have the sphere of Spirit, Technocrats instead have the sphere of Dimensional Science, and view the spirit world through the lens of deep space, rather than spiritual travel. This does lead to the fun juxtaposition of Technocrat explorers outfitted in deep space protective gear walking the surface of “Mars” and encountering Gandalf walking around with no protection. Things like this is why Technocrats call Mages “reality deviants”.
It takes effort to pierce the wall between the material and the spirit world; werewolves have it easiest, able to “step sideways” through any reflective surface – werewolves are creatures of equal parts flesh and spirit, which is why it comes so easily to them. Mages require fairly deep knowledge of Spirit Magick and, often, also expenditure of magical “Quintessence”. Technocrats use science – rocketry, usually – which comes with its own great cost in effort, maintenance, and fuel (Technocrats do frequently use fuels that are essentially the same thing as magical Quintessence).
The sphere of “consensual reality” wherein the world obeys the laws of physics and holds off the spirit world has steadily grown over the centuries; in the modern day setting of the game, it extends out to slightly beyond geosynchronous orbit. Beyond that, space isn’t “space”, per se, but in fact is part of the spirit world. Our deep space probes are essentially all magical artefacts.
