This planet is a deathworld. Spirits and environment warp each other. Big cities in the Empire are literally build with effectively terraforming wards. And nobody is gonna bother with installing too many of those in the sewers. These are not "Old cities and old sewers" they are basically Fantasy colony cities.
So its a sewer on a deathworld and the terrorists are Cultivator Mole people from an underground society.
Well there is no hope of LQ sweeping the entire sewer, while there is hope that the Cultivators of the Ministry can act fast enough. Or what is them being Cultivators, Forces of Nature in the Making in your own words, not good enough now?
Cool, that would make the sewers even more ordered and easier to search, because they would have been designed with feng shui and all that.Because geomancy is an actual thing and we know CRX' dad is an urban planner unfucking the shit that the Hui let happen. Even if it's built for normal people the feng shui is a thing.
And as for the ministry having any cultivators as high as us on standby that's a big if. The only hope on the front are the local nobles and how long it takes to get enough of those together is guesswork at best.
And yes, initiative matters massively because if we can even just quarter the things that awaken instead of having to fight all with help we will be much better off.
