Writing worlds is a bit of a tricky thing. I haven't tested Dungeons, Strongholds, or Mineshafts yet, but things like Ores occur normally in the world. If you make a descriptive book without any pages, it'll randomly generate the world, including how stable it is.

I always go for the Charged symbol in my written ages, as it adds stability to the age. Of course, you will run the risk of being struck by lightning....but hey, lightning never strikes twice right?
