In my story, there's the Orbittal Striker, a feature attached to an anti matter-fueled satelite, that can fire laser beam that can vaporize small islands in the weakest setting. It is the seventh most powerful object in my entire verse and THE most powerful weapon the human race from the protagonists' time has created.
The problem here is that it is far more powerful than nuclear weapon and why would the international community allow construction of such dangerous potential weapon like that? For your information, the global community is somewhat aware of supernatural phenomenas, including several invasions of enormous and hostile extraterrestrial creatures called The Deviations. However, because the military in my verse is extremely competent,
there hasn't been any use for the device.
It is ALMOST used at the climax of the first arc, where the protagonists' city is about to swarmed and assimilated by virus/alien demon creatures, and is definitely used near the end of the story to obliterate
the gate to the Otherworld and its Sentinel
at the same time.
I have no idea what kind of financial and political implication will arise from constructing and using such devices. Any thing I should take into consideration?
