That makes sense for some things, where such structures would be actually erected. I didn't even know the 'point of interest' flags were IC at all, as it seems more than passing strange that these flags should pop up all over the place, including the ones where you have to fight vicious creatures just to get to. How did the girl scouts get there in the first place? The "Grand Canyon in the swamp" thing is why I thought they were OOC presents for exploring and discovering places that were part of history, to intrigue PCs and make them ask around and stuff.
If there were actually supposed to be flags waving around in the Rift and the Underdark this whole time, could we change it to something other than these ubiquitous banners and instead put something more appropriate depending on the location, for the plaque and statue reference? For instance, the statue of Arenski at the Great Library is technically its 'point of interest' flag, right? Why would we have these monuments with actual plaques and have a little flag waving saying "this is a point of interest!" for tourists? hehe. It's just an example... just suggesting to make the statue the flag, if that makes any sense... something that is tangible IC.
Not sure that was any less jumbled *squints an eye*
