This is purely crazy hindsight of my part, but after having made the observation for the first time just now I am curious to know how many people have noticed that these knights are carrying minerals inside Haven's Bazaar in this screenshot within the About page.
In other words, the About page in general.
Just a image crafted before the game released, probably they had some other ideas in mind before the game launched. Maybe a way to win by not actually killing everything in your wake? But mercy is overrated as always, better snuff out the miserable lives of those Gremlins and devilites, whose lives are probably crap anyways.
