This from a post regarding Patrick Stuart's upcoming book, Queen Mab's Palace. I’m looking forward to reading it, as his Deep Carbon Observatory was one of the very first OSR products I ever read, and Patrick’s work continues to be appointment reading.
The above excerpt reminded me of an interesting question to consider when running RPG sessions; how do people give directions in the fictional world? This is worthwhile to think about both in the sense of NPCs giving PCs literal directions, and in the sense of how the DM describes imagined spaces to the PCs so they can visualize them accurately. So what are some options?
Locally relative. Until recently in human history, most people did not have GPS, compasses, or even detailed maps. Most directions would be given based on a simple view of the sun and some dead reckoning using local landmarks. This is a good baseline assumption for low-tech worlds like most fantasy milieus. Simple questions of elevation and sight lines would greatly affect how well the local area is "known" to inhabitants.
Map-level view. The opposite is people who primarily have a “map-level” view, rather than an egocentric sense of direction. This is generally better for PCs trying to ask for directions, as the players themselves are to some degree viewing the action “top-down” (literally or figuratively) when trying to get from place to place. So an NPC who can tell them to go west is probably more helpful than one who gives locally relative directions.
But it can get tricky for the PCs in other circumstances. If a PC deep in a dungeon asks an NPC “which door should I use, the one on the right or the one on the left?” and the answer they get is “the westernmost one,” that PC may wish they had those locally relative directions.
Intuitive directions. The direction-giver knows how they would get there, using subtle clues from the weather, the disposition of local flora and fauna, or even something like the planet’s magnetic field. But that can’t be relayed in a way the PCs will realistically understand. This is a good way to prompt the PCs to hire a guide who can navigate for them. And to stress that they need to keep that guide alive.
Different units of measurement. The locals know how far it is to where you want to go, but they don’t use the same units of measurement and don’t know how to convert to units the PCs understand. This can create a bit of a puzzle, where the PCs are rewarded for figuring out something that must have been a challenge for real-world explorers as well.
Different or differently emphasized sensory organs. What happens when a PC uses Speak with Animals to ask a bat about the interior of a cave? The bat knows the cave in great detail, but not in the way a person would know it. Imagine the poor bat trying to explain how echolocation feels to someone who cannot echolocate.
Weird environment. If PCs are exploring a strange space like the astral sea, and they meet a resident of that place, how does that creature explain how to get where they want to go? Light? Gravity? Something else?
Be Kind to Your Players
It is fun to bake your crazy ideas into your game, but please keep in mind that TTRPGs are a matter of mediating a highly fluid and unstable imagined environment through mostly just... words. Be careful when throwing in advanced concepts like tricky or hard-to-understand directions. Err in favor of the players when they’re struggling with confusion that is more about the distance between player and character than any intentionally crafted game challenge.
