The Blue Elfstones, commonly known as the Elfstones or Seeking Stones, are an Elven magic from the Age of Faerie. Like all Elfstones, they can be used as a weapon against creatures of magic, they draw their strength from their user, and they can only be used by those with sufficient Elven blood and those to whom they have been freely given. Different colors of Elfstones also have specific, additional uses: the blue Elfstones in particular can be used in finding a lost item, a way out of a forest, or anything else the user seeks.
