To be as brief as possible I have a setting in the far future. This setting has various races, most resembling humanity to the point that with only a cursory glance you couldn't tell one from the other.
There are only 2 races native to the universe with all the others essentially being refugees from other realities.
The question is, the native races are if left unchecked, willing and possesing access to certain skills are capable of destroying entire planetary infratructures within the space of a few hours but only if they obtain access to certain technology.
It's comparable to a nuke. It's difficult to make, easy to track but if someone gets their hands on it and can break the security locks a single person can destroy a civilization with almost no time to react. Other races have their own little WMDs none provide such an easy target.
I should probably touch on what this tech does and that is... create matter and energy and convert them freely from one to the other (liberally applying all the handwavium on that one)
The only real limitations on this tech are
1 - It can only be used by the native races.
2 - It can only affect matter and energy generated by it. So no turning random objects into world ending objects.
3 - Each unit of this tech can not be manufactured without a fragment of a security AI. There aren't that many of these fragments left anymore.
So how would various civilizations react to such a threat from their own citizens. Theocracies, Dictators, Republics, Oligarchies, Technocracies etc. How would various governments react to/control this?
This is my first post so sorry if I don't quite get how the site works yet but thank you for your time.
