Game ideas inspired by the Yukon's forest of signs

 While driving north to Alaska, we passed through Watson Lake in the Yukon. That hamlet hosts a great "forest of signs" - somewhere now between 90-100,000 signs nailed, screwed, strapped, etc. to trees and posts in a massive collection that has been growing since the mid-20th-century. I expected a rather small affair, and was blown away by wandering the aisles and lanes (!) of this small 'forest.' 

It got me thinking about why a similar collection might grace a fantasy gaming universe. Here are some ideas. 

+ Like Borges' infinite library, the forest of signs is a legendary mystical archive recording the location of every discrete place that exists in the world -- even places utterly lost and forgotten. Not sure whether the tomb of the Fourteenth Emperor was ever constructed, or how to find it? You'll know if you find it's placard in the Forest of Signs, though the three billion other signs might slow you down a bit...good luck with the random encounter rolls while you search.

+ By official decree, all communities that yield to the Glorious Benevolence of Empire mark their submission by sending delegates to post, and later maintain, their community signpost in the Forest of Signs just outside the great capital. Of course, the Empire's rival districts measure their dignity by the lavishness of their respective signs, and harried imperial administrators have been known (or so it's said) to base regional appropriations not on the mountains of paper notes sent to the capital but simply upon the size and appearance of various signs. This makes having a better sign than rival cities of great importance. The place is well-guarded during visiting hours, but after dark, the Forest of Signs becomes a hotbed of gold-leaf-thieves, vandals, would-be-repair workers, and other adventurers paid well to boost one or another city's status. 

+ Or no, perhaps we're taking all this too literally. The Forest of Signs isn't about signposts to places; it's about Semiotics. In fact, the "Forest" lies at the world's edge, and the 'signs' posted here are guides to the mystic resonances between things, ideas, and the word-not-word signs/signifiers/etc. used to (try to) communicate with reality through the Language of Magic. As all wizards and magic-users know, graduation to the next degree of mystic mastery ('leveling up' cough cough) always requires a fresh venture into the Forest, to learn and master a new set of potentially meaningful correspondences. But the Forest can be deadly, so maybe bring some friends? 

Huh.
