Until the develop of modern physics and the resulting study of electrodynamics most people were comfortable with the fact that lightning never struck the same place twice. Ars is a game in mythic europe where modern science and our "enlightened" views of the world and reality have no place. This made me wonder. How true/real are these mediveal "facts" in mythic europe?
Lets say the players are cought outside in an open field during a naturally occuring lightning storm. They notice that lightning strikes a very tall tree standing on top of a very tall hill rich in iron deposits. Naturally they rush towards the tree to seek shelter, comfortable with the knowledge that they can't possibly be struck by lightning there.
Now what happens in mythic europe? Are they safe? Or do they discover much to their dismay that lightning DOES strike the same place twice?
