well, according to the legend, you can see your future, but you have to fast alone in darkness for a week and then wander out into the night looking for the church. On your way there are many strange creatures in the woods who will try to test you, the watchers, and if your not pure in spirit, you die before morning. if you make it to the church you walk around it in a pattern and the night raven will reveal part of the future. its called year walking and can only be gone on very special religious events when there is fault in the Dimensions and watchers can walk the earth.
this, of course, is just a legend but i think its fascinating and a year or two a go i researched it, coming up with very little, however there is a game called year walking and if your smart enough, it puts together all the pieces and is a great game.
