After reading this thread about the poor legibility of the floor glyphs in Kroshkkur (I always did wonder what those blank squares of dirt were supposed to be), I have a better idea what you're going for here. And we already have an example of glyphs appearing in dialog text (the lore note in the Occult Egress), so there's precedent. Now, the code that puts the glyphs on the floor was clearly not written with the expectation that anyone else would need to know what glyph was on the floor,Sinister Stairs wrote:
- I don't believe the Occult Egress runes/codes count as landmarks; it'd be cool if the "Show Landmarks" list would show the actual glyph, because sometimes viewing them on the map can be difficult based on one's tiles size.

[Disclaimer: I've only tested this in Kroshkkur. When floor glyphs appear in other zones, do they also appear in a nice row like this? The glyph order does matter, after all, so I'd prefer to list them in the landmarks list in the proper order.]
