I was thinking, how about a nav spell simmilar to go but a bit more random.
It could work like this: At boot, random ley lines get drawn over the map.
They're invisible, but if you cast this spell, call it line travel or
something, you get zoomed along the line to it's end. Potentially you could
travel long distances very cheapely, but it would be random. Could also add
in a secondary spell to get an idea where a line goes, kind of like
stargazeing ("You sense that this line goes a bit north and a fair distance
east" type thing). Thanks for listening
