I have a feeling that this is far less original than I think it is, but I can't find it anywhere in my books that I have access to at the moment. I'm sure if I'm just copying from a sourcebook that I only remember fuzzily, they'll tell me.
The Way Stone
These devices are simple in both form and function. A flat bit of knapped flint pointed on one end, these devices are easily mistaken for arrow or spearheads from a technologically primitive tribe, though a detect magic spell will reveal a minor enchantment of divination. To use, one must simply hold them in the palm of one's hand and name a desired and known location. The stone will spin to point in the direction of that location.
Successful use of the stone is based upon how well known the desired destination is:
*Location known intimately to user (having physically visited for a period no less than 4 hours) - 95%
*Location known in passing (physically passed through on at least one occasion, but did not stay) - 85%
*Location described in detail (as from one who knows it intimately or from a text) - 75%
*Location known only vaguely or by reputation (have heard of location, but do not know any details about it) - 50%
*Location known only by legend or heresay (true existance unsure) - 10%
A failure indicates 50% of the time that the stone simply does not function and 50% of the time the stone will point to a random, incorrect location.
Note that the stone does not indicate passable routes, only the direction in which a point in space is situated. Thus, if asked to point in the direction of the center of the planet, it will point straight down and not at the location of a tunnel that will eventually lead to the center of the planet.
A very few (5%) of these devices will, in fact, point not to a location, but a passable route to reach that location. In the case of common towns, cities, castles, etc., the stone will likely point to a nearby road that will take the user towards their destination. If no road exists, or the "best" route is a direct, overland route, the stone will point in that direction. Asking the location of mythological locations, or locations that are not entirely within the confines of the Prime Material plane will likely generate a prosaic response similar to a Divination spell: helpful, but likely not direct or straightforward.
