2 lines of text does not require a writeup - we are talking "this is Milara's throne" and "this was the dude that summoned the dragoncalled" here, not encyclopedias.
The flag, agreed, does not make sense - it is actually the place that is supposed to be important in some way, as they all mark a location where something worth knowing happened (edit - or where someone interesting lives or lived) ... just don't give you a clue what that something was.
Edit - As an aside, I really don't know why the problem is the lack of information, as most of those areas have many events tied to them, regardless of official writeups existing for them or not. 2 lines of text does not require a writeup - we are talking "this is Milara's throne" and "this was the dude that summoned the dragoncalled" here, not encyclopedias.
This is exactly what I'm suggesting and why. A clue as to the areas significance in history would be nice. Nothing lengthy is needed, just some reference that could be looked up in Lore if it was wanted.
Just checking: these bits of rumor/legend/whatever would be displayed for any character, right? I can't speak for everyone who plays a single character rather than a rotating stable of them, but I'd like to see the little stories, too, and it would suck to miss out just because Jennara's been somewhere before.
