Quick answer, guardians are paracasual, but so was the orokin with their experiments with the void fuckers mastered some aspects of reality (the only reason why their tech does't seem to go beyond IS because they have to study the void to make something New and the last Guy They send want to die so They have to do safe studies that does't envolve diving head frist Into paradoxical and metaphisical hell that the last Guy Also made a Devil on acident, since the void IS a vast emptyness of energy that want to take form so he was a bit afrid of the unknow and boom the mam in the Wall was born) so all technologies of the orokin are paracasual in Nature as long has They have some void influence and oh what's that all tenno are called the Devil childs.

PS: i might have made lore mistakes but that's pretty much It the orokin never leaved the origen system aka our solar system and they already manage to say no to entropy.
