Perfect simple item. I think these are absolutely rife in Skyrim :)
Mystic Moons idea is probably the best way to use these, but one could add complications to their use. It is possible to create multiple marker stones and some may draw the user to traps or dangerous areas. I would have these always lead to perilous adventure, and be found occasionally in treasure.
In truth, the original gloves upon which these were modeled where the Hands of Order, stolen ironically from a long dead god of Law. The touch of the glove would remove chaos from that touched, taking them from unorganized and primitive to ordered. The touch is especially baneful to beings of chaos and entrophy, but nothing is unscathed by prolonged contact.
