I always wondered about the dimensions of a leyline! I mean - the length varies, obviously, but how wide are they? Would a 0.3 HB on a 25k map would create a leyline a few centimetres wide? Or maybe a few millimetres?
I've heard that these things can be powerful, but melting your spade? As the Spice Girls used to screech: "Earth Power!" Or something.
