Eh, personally just found it off to turn our sword into something like that. Some could see it that way, others could see it another, that was more to what I was trying to get at. Like, I'm all for doing cool stuff for whatever reason, even if its impractical or not cost effective (vs what some other people in this thread might say), But that just seems kind of... I dunno, meh? As a symbolic act, feels tame and can come off as off-putting, as I said before.
On the impractical but totally cool side of things, feels like it'd be better to just make something like an imperial gardens (something like the hanging gardens) and then plant our sword mastersword style in the center. So its more, we fought and laid down our arms, but if push comes to shove, we'll pick it up again, that kind of thing.
Was originally just tossin' in my two cents on 'that seems like a weird idea that may come off as strange.' I'm not the kinda person who puts things in boxes and anything that doesn't fit in the box is heretical, and like I said, I can see where you're coming from... as an action, would probably be the same as the brewery, in a chance to raise or lower opinion.
I'd really just put the matter to bed, since I don't see much of a point in discussing what to do with our sword at the moment. Tossed in the reforging of the sword as a possible alternative, since I like compromise.
