re: perceived use! i think it'd be interesting to be able to use them to locate different arehtei-based lands, since that's the kind of direction the game is going at the moment -- they can have different uses as time goes on, keep a flexibility in with it, but i think it'd be interesting for the time right now! even the natives can join in with their simpathis-aligned crystals if it gets to that point

(and to open things like they did in that cavern that one of the groups went to with the mechanical creature and the broken statue that had a claw left over. that one. white was part of it that's how i remember this)
