+-------------------------------------------------------------------------+OK, one more word on compasses, and that's it. I propmise.
All credit to Owen Jones for being prepared to take a fall over his contention of my three-compass theory, but:
You in fact only need two, so long as you can triangulate the distance to one of the compass points! This requires you to be close enough to move a measureable angle relative to one of the points within a reasonable time, though.
Apologies for using the obscure (but worthy) PNG format for my diagram - it's a PCX now.

I like this idea, I don't know if it's in any way official, but must be true at least in some Orlanthi areas. It feels right.
